The TLV9042IPWR from TI is a dual rail-to-rail I/O op-amp with 350kHz GBW, ultra-low 10uA/ch current, and 1.8-5.5V supply in TSSOP-8 for battery-powered signal conditioning.

The TLV9042IPWR is a dual-channel nanopower rail-to-rail I/O CMOS operational amplifier with 10uA supply current per channel. The input stage uses a differential PMOS pair with chopper stabilization to minimize 1/f noise and input offset voltage (typically 0.4mV). Rail-to-rail input is achieved through a complementary input stage that smoothly transitions between PMOS and NMOS pairs across the common-mode range. The output stage uses a class-AB CMOS push-pull configuration that swings within 10mV of either supply rail under light load. The 350kHz gain-bandwidth product and 0.16V/us slew rate are optimized for low-power applications. Internal compensation (dominant pole at approximately 200Hz) ensures stability with capacitive loads up to 100pF without external compensation.
