AD5314ACPZ-REEL7

Digital To Analog Converters Overview

The AD5314ACPZ-REEL7 is a quad 10-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V and reducing to 80 nA in power-down mode. The device features four independent DAC channels with rail-to-rail output buffer amplifiers and a slew rate of 0.7 V/μs. It utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz. Key specifications include ±4 LSB INL for the A version, a typical settling time of 9 μs, and an operating temperature range of −40°C to +105°C.

Digital To Analog Converters Feature Summary

• Quad 10-bit resolution with ±4 LSB Integral Nonlinearity (INL) for the A version
• Low power consumption: 500 μA at 3 V, 600 μA at 5 V; 80 nA in power-down mode
• Rail-to-rail output buffer amplifiers with 0.7 V/μs slew rate
• 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment
• Programmable voltage and current sources
• Industrial process controls

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ACPZ' corresponds to the 10-lead LFCSP package and industrial temperature grade (-40°C to +105°C). Confirm that the 'REEL7' designation indicates tape-and-reel packaging. Ensure compatibility with external reference voltages between 0.25 V and VDD, as the internal reference input is not buffered.

Digital To Analog Converters Selection Notes

Select the AD5314ACPZ over the AD5304 or AD5324 when 10-bit resolution is required. Choose the 'A' version for ±4 LSB INL or the 'B' version for ±2.5 LSB INL if higher accuracy is needed. Ensure the application supports the 3-wire serial interface timing requirements, specifically the minimum SYNC high time and data setup/hold times specified in the datasheet.

Digital To Analog Converters Part Context

The AD5314 is part of the nanoDAC family, sharing the same pinout and interface as the 8-bit AD5304 and 12-bit AD5324. This allows for design flexibility across different resolution requirements within the same physical footprint (10-lead MSOP or LFCSP). The device is qualified for automotive applications and includes a power-on reset function to ensure outputs start at 0 V.

Digital To Analog Converters Replacement Considerations

The AD5314BRMZ is a direct replacement offering improved linearity (±2.5 LSB INL) in the same MSOP package. For LFCSP packages, the AD5314ACPZ-RL7 is available. Verify that any substitute maintains the 3-wire serial interface compatibility and power supply range.
