Additional Details

The AD7686BRMZREEL7 operates from a single 2.5 V supply. The device contains a low-power, high-speed, 16-bit sampling ADC with no missing codes, a conversion clock, a reference (internal and external), and a versatile serial interface. The ADC features a pseudo differential analog input. It accepts analog input voltages from 0 V to VREF. The reference voltage (VREF) can be supplied externally, or it can be derived from the internal reference. The device features an automatic power-down mode that reduces power consumption when not actively converting. The serial interface is SPI-/QSPI-/MICROWIRE-/DSP-compatible. The AD7686BRMZREEL7 is available in a small, 8-lead MSOP package and is specified for operation from −40°C to +85°C.
