The AD5601/AD5611/AD5621 belong to the AD5601/AD5621nanoThe DAC family, which is a single, 8-/10-, 12-bit, buffered voltage output DAC®, operates from a single 2.7 V to 5.5 V supply, consumes 75 μA typical at 5 V, and is available in a small LFCSP and SC70 package. These devices contain on-chip precision output amplifiers that enable rail-to-rail output swing. THE AD5601/AD5611/AD5621 FEATURE A VERSATILE 3-WIRE SERIAL INTERFACE CAPABLE OF OPERATING AT CLOCK RATES UP TO 30 UMHz and are compatible with spi, qspi,™ microwire™, and dsp interface standards.
All three devices derive their reference voltages from the power input, resulting in the widest dynamic output range. Each of these devices has a built-in onePower-on reset circuit, ensure that the DAC output powers up to 0 V and maintains that level until a valid write is performed on the device.
It also features a power-down feature that reduces the typical power consumption of the device to 0.2 μA at 3 V in power-down mode and provides a software-selectable output load. Shutdown mode can be entered through the serial interface.
In normal operating mode, these devices feature low power consumption, making them ideal for portable battery-powered devices. thesenanoDAC devices combine a small package with low power consumption, making them ideal for meeting level-setting requirements, such as biasing or controlling voltages in space-constrained, power-sensitive applications.
Product features
- Available in 6-pin LFCSP and SC70 packages.
- Low power consumption, single-supply operation. The AD5601/AD5611/AD5621 operate from a single 2.7 V to 5.5 V supply and consume 100 μA maximum, making them ideal for battery-powered applications.
- Using an on-chip output buffer amplifier, the DAC provides rail-to-rail output swing with a typical slew rate of 0.5 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. When turned off, the DAC has a typical power-on reset current of 0.2 μA at 3 V with brownout detection.
