AD5694RBCPZ-RL7

Overview

The AD5694RBCPZ-RL7 is a quad, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device uses a 400 kHz I2C-compatible serial interface and includes a GAIN pin for selectable full-scale outputs of 2.5 V or 5 V. Key performance metrics include ±1 LSB maximum relative accuracy (INL), ±0.1% FSR gain error, and a low glitch impulse of 0.5 nV-sec. It supports power-down modes reducing current to 4 µA and offers hardware reset options.

Feature Summary

Quad 12-bit resolution with ±1 LSB maximum INL and guaranteed monotonicity
Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient
User-selectable gain (×1 or ×2) via GAIN pin for 2.5 V or 5 V full-scale output
Power-on reset circuit with RSTSEL pin for zero-scale or midscale initialization

Applications

Optical transceivers
Base-station power amplifiers
Process control PLC I/O cards
Industrial automation systems
Data acquisition systems

Procurement Notes

Verify the B-grade specification limits against application requirements, particularly regarding offset and gain error tolerances. Confirm the LFCSP-16 package thermal characteristics match the PCB layout design. Ensure the I2C address pins (A0, A1) are configured correctly to avoid bus conflicts in multi-device systems.

Selection Notes

Select this component when a quad-channel DAC with high precision and low power consumption is required. The internal reference eliminates external component count, while the I2C interface simplifies microprocessor connectivity. Consider the B-grade accuracy if cost sensitivity allows, otherwise verify A-grade specifications for tighter tolerance requirements.

Part Context

This part belongs to the AD5696R/AD5695R/AD5694R family, differentiated by resolution: 16-bit, 14-bit, and 12-bit respectively. All variants share identical pinouts, interfaces, and reference architectures. The AD5694R provides the highest channel density for applications where 12-bit precision is sufficient.
