AD7689BCPZ Description

Short technical summary and product information.

The AD7689BCPZ is a 16-bit, 8-channel, 250 kSPS successive approximation register (SAR) analog-to-digital converter from Analog Devices. It is part of the PulSAR family and offers a charge redistribution architecture with no missing codes. The device supports multiple input types: differential, pseudo-differential, and single-ended.

 

Key electrical specifications include a typical INL of ±0.4 LSB, SINAD of 92.5 dB at 20 kHz, and THD of −100 dB at 20 kHz. The ADC features a dynamic range of 93.8 dB and operates from a single 2.3V to 5.5V supply. Power dissipation is 3.5 mW at 2.5V/200 kSPS and 12.5 mW at 5V/250 kSPS, with a standby current of 50 nA.

 

The device includes an internal temperature sensor, a channel sequencer, and selectable 1-pole filter. It uses a serial interface compatible with SPI, MICROWIRE, QSPI, and DSP. The reference can be internal (2.5V or 4.096V) or external.

 

The AD7689BCPZ is available in a 20-lead 4 mm × 4 mm LFCSP package (20-LFCSP) and is intended for surface mount assembly. It is suitable for applications such as multichannel system monitoring, battery-powered equipment, medical instruments, and data acquisition systems.
