1 MHz gain-bandwidth, 20 µV offset — precision DC performance in a compact SOT-23-5
The OPA202IDBVR is a single-channel general-purpose operational amplifier from Texas Instruments, offering a gain-bandwidth product of 1 MHz and a slew rate of 0.35 V/µs. With a maximum input offset voltage of 20 µV and input bias current of 250 pA, this op-amp is suited for precision DC signal conditioning in sensor interfaces, data acquisition, and control loops where external nulling is undesirable. The supply voltage range spans 4.5 V to 36 V, supporting both single-supply (e.g., 5 V or 24 V industrial rails) and split-supply configurations (±2.25 V to ±18 V).
Industrial temperature range and active production status
The OPA202IDBVR is an active-production device rated for the -40°C to 125°C industrial temperature range, making it suitable for factory-floor and outdoor equipment where ambient temperatures vary widely. The part is ROHS3 compliant and supplied in a standard SOT-23-5 package, which is a common footprint for compact PCB layouts in motor drives, PLC analog input modules, and temperature transmitters.
580 µA supply current and 35 mA output drive — power budget and load considerations
Quiescent current is 580 µA per amplifier, which keeps the thermal contribution low in multi-channel designs and extends battery life in portable instrumentation. The output stage can source or sink 35 mA, enough to drive the analog input of a typical SAR ADC, a small relay coil, or a 4-20 mA transmitter loop directly without a separate buffer.
