AD5320BRMZ

Digital To Analog Converters Overview

The AD5320BRMZ is a single-channel, 12-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply and consumes 140 μA at 5 V. The device features an on-chip rail-to-rail output buffer amplifier with a slew rate of 1 V/μs. Its reference is derived directly from the power supply input, eliminating the need for an external reference pin. The part includes a power-on reset circuit that ensures the DAC output initializes to zero volts upon power-up.

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity by design
• Rail-to-rail output swing capability via on-chip buffer amplifier
• Low power consumption: 140 μA in normal mode, down to 200 nA in power-down
• 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the package type matches the specific suffix; the BRMZ designation indicates an 8-lead MSOP package. Confirm the temperature range corresponds to the 'B' grade specification (-40°C to +105°C). Ensure the ordering code aligns with the required tape-and-reel or tube packaging format as specified in the manufacturer's ordering guide.

Digital To Analog Converters Selection Notes

Select the AD5320 when a single-channel, 12-bit resolution is required with rail-to-rail output swing. It is suitable for applications where power supply-derived references are acceptable. Compare against the AD5300 (8-bit) and AD5310 (10-bit) if lower resolution suffices. Ensure the system logic levels are compatible with the Schmitt-triggered inputs for the serial interface.

Digital To Analog Converters Part Context

The AD5320 is part of a family of pin-compatible DACs that includes the AD5300 and AD5310. These devices share identical pinouts and package options (6-lead SOT-23 and 8-lead MSOP), allowing for design flexibility across different resolution requirements without altering the PCB layout. The AD5320 represents the highest resolution option within this specific low-power series.

Digital To Analog Converters Replacement Considerations

The AD5300 and AD5310 are pin-compatible alternatives offering 8-bit and 10-bit resolutions respectively. For higher performance requirements, consider the AD5327 or AD5340 families. Verify that any substitute maintains the 3-wire serial interface compatibility and similar power consumption characteristics.
