Overview
The AD7303BRMZ is a dual, 8-bit voltage output digital-to-analog converter (DAC) operating from a single +2.7 V to +5.5 V supply. It features on-chip precision output buffers that allow rail-to-rail output swing with a typical settling time of 1.2 μs. The device utilizes a versatile 3-wire serial interface compatible with QSPI, SPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. Internal or external reference capabilities are selectable via the control register. Power consumption is typically 2.3 mA at 3.3 V, reducing to less than 1 μA in full power-down mode.
Feature Summary
- Dual 8-bit DACs with rail-to-rail output buffering
- 3-wire serial interface compatible with SPI, QSPI, and Microwire
- Internal or external reference selection via control register
- Individual DAC power-down capability for low power operation
Applications
- Portable battery-powered instruments
- Digital gain and offset adjustment circuits
- Programmable voltage and current sources
- Programmable attenuators
Procurement Notes
Verify the RM-8 microSOIC package designation for the BRMZ suffix against the manufacturer's ordering guide. Confirm the B version temperature range of -40 °C to +105 °C matches the application requirements. Ensure ESD precautions are observed during handling due to the device's sensitivity.
Selection Notes
Select this component when dual independent 8-bit voltage outputs are required in a compact 8-pin package. The internal reference simplifies design by eliminating external reference components, though an external reference can be used for higher precision. Ensure the host controller supports the 3-wire serial protocol or bit-banging for SYNC, SCLK, and DIN signals.
Part Context
The AD7303 belongs to Analog Devices' family of low-power, single-supply DACs. The BRMZ variant specifically denotes the industrial temperature grade (-40 °C to +105 °C) housed in the microSOIC (RM-8) surface-mount package. This packaging offers a smaller footprint compared to standard SOIC or DIP options while maintaining the same electrical characteristics.
Replacement Considerations
The AD7303BRM is the non-reel equivalent in the same microSOIC package. For different packages, the AD7303BR (SOIC-8) and AD7303BN (DIP-8) share identical electrical specifications but differ in physical form factor.
