Product Overview
LM2902DR is a Texas Instruments quad operational amplifier for Signal_Chain use. The LM2902 family device description identifies four amplifiers in the device, allowing multiple analog signal paths to be implemented in one package. The input common-mode capability includes the negative rail, and the differential input drive capability extends up to the supply voltage.
The recommended supply voltage range is 3 V to 26 V, with an operating ambient temperature range of -40°C to +125°C. At 25°C, the LM2902 has a maximum input offset voltage of ±7 mV and an input bias current of 20 nA typical, 250 nA maximum. Recommended common-mode voltage operation is 0 V to VCC - 2 V.
LM2902DR uses the D package, a 14-pin SOIC measuring 8.65 mm × 6 mm. Pin 4 is the positive supply, and pin 11 is the negative supply or ground for single-supply operation. Thermal data for the SOIC-14 package includes 99.3°C/W junction-to-ambient resistance and 60.4°C/W junction-to-case top resistance.
