Product Overview
LM2904DR is a Texas Instruments dual operational amplifier for Signal_Chain use. The device integrates two amplifier channels and is offered in the D package, an 8-pin SOIC body measuring 4.9 mm × 6 mm.
Recommended operation covers a 3 to 26 V supply range, with VS defined as V+ minus V-. The operating ambient temperature range is -40 to 125 °C, and the recommended common-mode voltage range extends from V- to V+ - 2 V. Electrical reference parameters include ±7 mV maximum input offset voltage at TA = 25 °C, 20 nA typical and 250 nA maximum input bias current, 0.7 MHz gain bandwidth product, and 0.35 mA typical supply current per channel.
For board and assembly review, the 8-pin package assigns OUT1 to pin 1, V- to pin 4, and V+ to pin 8. V- may be the negative supply or ground in single-supply operation. Thermal data for the D package includes 124.7 °C/W junction-to-ambient resistance and 66.9 °C/W junction-to-case-top resistance.
