AD7985BCPZ-RL7

AD7985BCPZ-RL7 Description

The AD7985BCPZ-RL7 is a high-performance, 16-bit, 2.5 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc. Designed for precision applications, it operates with dual supply voltages (2.375V to 2.625V for both analog and digital domains) and features a flexible SPI/DSP-compatible interface. Part of the PulSAR® series, this ADC integrates a 1:1 sample-and-hold (S/H) architecture, ensuring accurate signal acquisition. Packaged in a compact 20-lead LFCSP and delivered in tape & reel (TR), it is ideal for space-constrained designs. The device supports external or internal reference options, enhancing design versatility while maintaining ROHS3 compliance and REACH unaffected status.
