Describe：LPV812DGKR is a dual-channel, ultra-low power, precision operational amplifier launched by Texas Instruments (TI), belonging to the LPV81x series. It is specifically designed for "normally open" sensing applications in battery-powered wireless devices and low-power wired devices. This device operates with an ultra-low power consumption of only 425nA (per channel), yet it still offers an 8kHz gain bandwidth product and excellent DC accuracy. The maximum input offset voltage is only 300µV, and the temperature drift is 1µV/°C. It features a CMOS input stage with an input bias current as low as 100fA, making it highly suitable for applications with high source impedances. The input stage can detect negative power rails and has a rail-to-rail output, thereby maximizing the dynamic range at low voltages. Additionally, this device integrates EMI protection functionality, effectively reducing interference from external RF signals such as those from mobile phones and WiFi. It adopts an 8-pin VSSOP surface mount package, with a working voltage range of 1.6V to 5.5V and a working temperature range of -40°C to +125°C.
