AD5696ARUZ

Overview

The AD5696ARUZ is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It operates on a single 2.7 V to 5.5 V supply and features a 2-wire I2C-compatible serial interface with clock rates up to 400 kHz. The device guarantees monotonicity by design and offers high relative accuracy with a maximum integral nonlinearity of ±2 LSB at 16 bits. Key performance metrics include a total unadjusted error of ±0.1% FSR, an offset error of ±1.5 mV, and a low glitch impulse of 0.5 nV-sec. It supports user-selectable gain settings of 1 or 2 via the GAIN pin.

Feature Summary

• Quad 16-bit resolution with ±2 LSB maximum INL
• I2C-compatible 2-wire serial interface supporting 400 kHz
• Total unadjusted error of ±0.1% FSR and offset error of ±1.5 mV
• Power-on reset circuit with RSTSEL pin for zero-scale or midscale initialization

Applications

• Digital gain and offset adjustment
• Programmable attenuators
• Process control PLC I/O cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the specific grade (A or B) required for the application, as specifications such as INL and power consumption vary between grades. Confirm that the TSSOP-16 package meets thermal and mechanical constraints. Ensure the external reference voltage and logic levels are compatible with the device's operating range before ordering.

Selection Notes

Select the AD5696ARUZ when four independent 16-bit channels are required in a compact form factor. Choose this part over the AD5694 if higher resolution is necessary. Consider the AD5696R variant if an internal reference is preferred. Verify that the system can accommodate the external reference input and that the I2C bus speed requirements do not exceed 400 kHz.

Part Context

The AD5696ARUZ belongs to the nanoDAC+ series, which integrates DACs with output amplifiers. It is functionally similar to the AD5696 but distinguished by its TSSOP-16 packaging and external reference configuration. It serves as a high-precision alternative to lower-resolution DACs in multi-channel applications requiring tight DC accuracy.

Replacement Considerations

The AD5696BRUZ-RL7 is a direct replacement offering B-grade performance with tighter accuracy specifications. For applications requiring an internal reference, the AD5696ARUZ-R can be considered, though it may have different pinout or feature sets. Always verify electrical parameters against the specific datasheet revision.
