AD7980BRMZ

AD7980BRMZ Description

The AD7980BRMZ is a high-performance, 16-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc.'s PulSAR® series. Designed for precision applications, it operates with dual supply voltages (2.375V to 2.625V for both analog and digital domains) and features an external reference, enabling flexible system integration. Housed in a compact 10-MSOP package, this ADC is ideal for space-constrained designs. Its 1:1 ratio of sample-and-hold (S/H) to ADC ensures accurate signal acquisition, while the SPI/DSP-compatible interface simplifies communication with microcontrollers or FPGAs. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
