General DescriptionThe MAX9945 operational amplifier features an excellentcombination of low operating power and low input volt-age noise. In addition, MOS inputs enable the MAX9945to feature low input bias currents and low input currentnoise. The device accepts a wide supply voltage rangefrom 4.75V to 38V and draws a low 400µA quiescent cur-rent. The MAX9945 is unity-gain stable and is capable ofrail-to-rail output voltage swing.
The MAX9945 is ideal for portable medical and industri-al applications that require low noise analog front-endsfor performance applications such as photodiode trans-impedance and chemical sensor interface circuits.
The MAX9945 is available in both an 8-pin µMAX® anda space-saving, 6-pin TDFN package, and is specifiedover the automotive operating temperature range(-40°C to +125°C).

Detailed DescriptionThe MAX9945 features a combination of low input cur-rent and voltage noise, rail-to-rail output voltage swing,wide supply voltage range, and low-power operation.The MOS inputs on the MAX9945 make it ideal for useas transimpedance amplifiers and high-impedancesensor interface front-ends in medical and industrialapplications. The MAX9945 can interface with smallsignals from either current-sources or high-outputimpedance voltage sources. Applications include pho-todiode pulse oximeters, pH sensors, capacitive pres-sure sensors, chemical analysis equipment, smokedetectors, and humidity sensors.
A high 130dB open-loop gain (typ) and a wide supplyvoltage range, allow high signal-gain implementationsprior to signal conditioning circuitry. Low quiescentsupply current makes the MAX9945 compatible withportable systems and applications that operate undertight power budgets. The combination of excellent THD,low voltage noise, and MOS inputs also make theMAX9945 ideal for use in high-performance active fil-ters for data acquisition systems and audio equipment.
Low-Current, Low-Noise Input StageThe MAX9945 features a MOS-input stage with only50fA (typ) of input bias current and a low 1fA/√Hz (typ)input current-noise density. The low-frequency inputvoltage noise is a low 2µVP-P (typ). The input stageaccepts a wide common-mode range, extending fromthe negative supply, VEE, to within 1.2V of the positivesupply, VCC.
Rail-to-Rail Output StageThe MAX9945 output stage swings to within 50mV (typ)of either power-supply rail with a 100kΩ load and pro-vides a 3MHz GBW with a 2.2V/µs slew rate. Thedevice is unity-gain stable, and unlike other deviceswith a low quiescent current, can drive a 120pF capaci-tive load without compromising stability.
Applications InformationHigh-Impedance Sensor Front Ends
High-impedance sensors can output signals of interestin either current or voltage form. The MAX9945 inter-faces to both current-output sensors such as photo-diodes and potentiostat sensors, and high-impedancevoltage sources such as pH sensors.
For current-output sensors, a transimpedance amplifieris the most noise-efficient method for converting theinput signal to a voltage. High-value feedback resistorsare commonly chosen to create large gains, while feed-back capacitors help stabilize the amplifier by cancel-ing any zeros in the transfer function created by ahighly capacitive sensor or cabling. A combination oflow-current noise and low-voltage noise is important forthese applications. Take care to calibrate out photodi-ode dark current if DC accuracy is important. The highbandwidth and slew rate also allows AC signal pro-cessing in certain medical photodiode sensor applica-tions such as pulse oximetry.

For voltage-output sensors, a noninverting amplifier istypically used to buffer and/or apply a small gain to, theinput voltage signal. Due to the extremely high imped-ance of the sensor output, a low input bias current witha small temperature variation is very important for theseapplications.
Power-Supply DecouplingThe MAX9945 operates from a +4.75V to +38V, VEE ref-erenced power supply. Bypass the power-supplyinputs VCC and VEE to a quiet copper ground plane,with a 0.1µF ceramic capacitor in parallel with a 4.7µFelectrolytic capacitor, placed close to the leads.
Layout TechniquesA good layout is critical to obtaining high performanceespecially when interfacing with high-impedance sen-sors. Use shielding techniques to guard against para-sitic leakage paths. For transimpedance applications,for example, surround the inverting input, and thetraces connecting to it, with a buffered version of itsown voltage. A convenient source of this voltage is thenoninverting input pin. Pins 1, 5, and 8 on the µMAXpackage are unconnected, and can be connected toan analog common potential, or to the driven guardpotential, to reduce leakage on the inverting input.
A good layout guard rail isolates sensitive nodes, suchas the inverting input of the MAX9945 and the tracesconnecting to it (see Figure 1), from varying or large volt-age differentials that otherwise occur in the rest of thecircuit board. This reduces leakage and noise effects,allowing sensitive measurements to be made accurately.
Take care to also decrease the amount of stray capaci-tance at the op amp’s inputs to improve stability. Toachieve this, minimize trace lengths and resistor leadsby placing external components as close as possible tothe package. If the sensor is inherently capacitive, or isconnected to the amplifier through a long cable, use alow-value feedback capacitor to control high-frequencygain and peaking to stabilize the feedback loop.

Figure 2. Input Differential Voltage Protection
Input Differential Voltage ProtectionDuring normal op-amp operation, the inverting and non-inverting inputs of the MAX9945 are at approximatelythe same voltage. The ±12V absolute maximum inputdifferential voltage rating offers sufficient protection formost applications. If there is a possibility of exceedingthe input differential voltage specification, in the pres-ence of extremely fast input voltage transients or due tocertain application-specific fault conditions, use exter-nal low-leakage pico-amp diodes and series resistorsto protect the input stage of the amplifier (see Figure 2).The extremely low input bias current of the MAX9945allows a wide range of input series resistors to be used.If low input voltage noise is critical to the application,size the input series resistors appropriately.
