The LTA2904H is a dual-channel industry-standard operational amplifier with supply voltage up to+40 V. The LTA2904H offers outstanding dc precision and ac performance, including low offset (±0.8mV typically), low offset drift (±7 μV/°C typically), 1.1 MHz bandwidth, and 40 nV/√Hz input voltage noise density at 1 kHz. Unique features such as differential input-voltage range to the negative supply rail, high output current (±30 mA), high capacitive load drive of up to 0.1 nF, and high slew rate (0.5 V/μs) make the LTA2904H a high-performance operational amplifiers for high-voltage industrial applications.

The robust design of the LTA2904H provides ease-of-use to the circuit designer: integrated RF/EMI rejection filter and high electro-static discharge (ESD) protection (2000V for HBM). The LTA2904H is optimized for operation at voltages from +4.5 V (±2.25 V) to +40 V (±20 V) over the extended temperature range of −40 °C to +125 °C.
