Overview
The AD7992BRMZ-1, produced by Analog Devices Inc., is a 12-bit, low power, successive approximation Analog-to-Digital Converter (ADC) with an I2C-compatible interface. This component operates from a single 2.7 V to 5.5 V power supply and features a fast conversion time of 2 µs. It includes a 2-channel multiplexer and track-and-hold amplifier capable of handling input frequencies up to 11 MHz. The AD7992BRMZ-1 is particularly notable for its low power consumption and automatic shutdown mode, which maximizes power efficiency by reducing current consumption to 1 µA when not converting.
