AD53101is a single, 10-bit buffered voltage output DAC that operates from a single 2.7 V to 5.5 V supply and consumes 115 μA at 3 V. It includes an on-chip precision output amplifier that enables rail-to-rail output swing. THE AD5310 FEATURES A VERSATILE 3-WIRE SERIAL INTERFACE CAPABLE OF OPERATING CLOCK RATES UP TO 30 UMHz and is compatible with standard spi,™ qspi™, microwire®, and dsp interface standards.
The reference voltage of this device is derived from the power input, so it has the widest dynamic output range. The device contains a power-on reset circuit that ensures that the DAC output powers up to 0 V and remains at this level until a valid write is performed on the device. It also features a power-down feature that reduces the device's power consumption to 200 nA at 5 V in power-down mode and provides a software-selectable output load. Shutdown mode can be entered through the serial interface.
In normal operation, the device features low power consumption, making it ideal for portable battery-powered devices. The power consumption is 0.7 mW at 5 V and drops to 1 μW in power-down mode.
The AD5310 is part of a family of pin-compatible DACs. The AD5300 is an 8-bit version and the AD5320 is a 12-bit version. The AD5300/AD5310/AD5320 are available in 6-lead SOT-23 and 8-lead μSOIC packages.
Product features
Available in 6-pin SOT-23 and 8-pin MicroSOIC packages.
Low power consumption, single-supply operation. The device operates from a single 2.7 V to 5.5 V supply and consumes 0.35 mW typical at 3 V and 0.7 mW at 5 V, making it ideal for battery-powered applications.
Using an on-chip output buffer amplifier, the DAC provides rail-to-rail output swing with a slew rate of 1 V/μs.
The reference voltage is derived from the power supply.
High-speed serial interface with clock rates up to 30 MHz. Designed for very low power applications. The interface powers up only during write cycles.
Shutdown function. In shutdown mode, the DAC typically consumes 50 nA at 3 V and 200 nA at 5 V.
