AD7985BCPZ Description

Short technical summary and product information.

The AD7985BCPZ is a 16-bit, 2.5 MSPS successive approximation analog-to-digital converter (SAR ADC) from Analog Devices. It features 16-bit resolution with no missing codes and a maximum throughput of 2.5 MSPS in TURBO high mode, or 2.0 MSPS in TURBO low mode. The device accepts a pseudo-differential analog input range of 0 V to VREF, with VREF up to 5.0 V, and supports external or internal references (4.096 V typical).

 

The ADC delivers an INL of ±0.7 LSB typical and ±1.5 LSB maximum, with SNR of 88.5 dB using the on-chip reference and 90 dB using an external reference. Power dissipation is 15.5 mW at 2.5 MSPS with an external reference, or 28 mW with the internal reference. The serial interface is SPI-/QSPI-/MICROWIRE-/DSP-compatible and supports logic supplies of 1.8 V, 2.5 V, or 2.7 V.

 

The AD7985BCPZ is offered in a 20-lead, 4 mm × 4 mm LFCSP package for surface mount assembly. It operates over a temperature range of -40°C to 85°C. Typical applications include battery-powered equipment, communications, automated test equipment, data acquisition systems, and medical instruments.
