The AD5662 is a® low-cost, low-power, single-channel, 16-bit, buffered voltage output analog-to-digital converter (DAC) that guarantees monotonicity.
The device has a built-in power-on reset circuit that ensures that the DAC output is powered up to 0 V or an intermediate level (depending on the model) and maintains that level until a valid write operation is performed. The device has a typical power consumption of 250 μA and also features power savings that reduce power consumption to 1 μA at 5 V in power saving mode and provides a software-selectable output load.
The AD5662 features a versatile three-wire serial interface that is capable of operating at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™, and DSP interface standards. It has a built-in on-chip precision output amplifier that enables rail-to-rail output swing.
Product features:
1. 16-bit monotonic DAC with 12-bit accuracy.
2. Available in 8-pin SOT-23 and 8-pin MSOP packages.
3. Power-up reset to zero or intermediate level.
4. Low power consumption. Operates from a 2.7 V to 5.5 V supply. Typical power consumption is 0.35 mW at 3 V and 0.7 mW at 5 V, making it particularly suitable for battery-powered applications.
5. Shutdown function. In shutdown mode, the DAC typically dissipates 50 nA at 3 V and 200 nA at 5 V.
6. Establishment time: 10 μs.
