Overview
The TLV9002IDDFR is a dual-channel, low-voltage operational amplifier (op amp) manufactured by Texas Instruments. It is part of the TLV900x family, which includes single, dual, and quad-channel variants. This op amp is designed for cost-optimized applications, offering rail-to-rail input and output swing capabilities and operating at supply voltages as low as 1.8 V and up to 5.5 V. The TLV9002IDDFR is packaged in an 8-pin SOT-23-THN (DDF) package, making it suitable for space-constrained applications such as smoke detectors, wearable electronics, and small appliances.
