Part Description: AD5302/AD5312/AD5322 2.5 V to 5.5 V 230 µA Dual Rail-to-Rail Voltage Output 8-/10-/12-Bit DACs Data Sheet (Rev. C)


Part Details:

2.5 V to 5.5 V, 230 A, Dual Rail-to-Rail, Voltage Output 8-/10-/12-Bit DACs AD5302/AD5312/AD5322 FEATURES GENERAL DESCRIPTION AD5302: Two 8-bit buffered DACs in 1 package The AD5302/AD5312/AD5322 are dual 8-, 10-, and 12-bit A version: ±1 LSB INL, B version: ±0.5 LSB INL buffered voltage output DACs in a 10-lead MSOP that operate AD5312: Two 10-bit buffered DACs in 1 package from a single 2.5 V to 5.5 V supply, consuming 230 A at 3 V. A version: ±4 LSB INL, B version: ±2 LSB INL Their on-chip output amplifiers allow the outputs to swing rail- AD5322: Two 12-bit buffered DACs in 1 package to-rail with a slew rate of 0.7 V/s. The AD5302/AD5312/AD5322 A version: ±16 LSB INL, B version: ±8 LSB INL utilize a versatile 3-wire serial interface that operates at clock 10-lead MSOP rates up to 30 MHz and is compatible with standard SPI®, Micropower operation: 300 A @ 5 V (including QSPITM, MICROWIRETM, and DSP interface standards. reference current) Power-down to 200 nA @ 5 V, 50 nA @ 3 V The references for the two DACs are derived from two reference 2.5 V to 5.5 V power supply pins (one per DAC). The reference inputs can be configured as Double-buffered input logic buffered or unbuffered inputs. The outputs of both DACs can be Guaranteed monotonic by design over all codes updated simultaneously using the asynchronous LDAC input. Buffered/Unbuffered reference input options The parts incorporate a power-on reset circuit, which ensures 0 V to VREF output voltage that the DAC outputs power-up to 0 V and remain there until a Power-on-reset to 0 V valid write takes place to the device. The parts contain a power- Simultaneous update of DAC outputs via LDAC down feature that reduces the current consumption of the Low power serial interface with Schmitt-triggered inputs devices to 200 nA at 5 V (50 nA at 3 V) and provides software- On-chip rail-to-rail output buffer amplifiers selectable output loads while in power-down mode. The low power consumption of these parts in normal operation APPLICATIONS makes them ideally suited for portable battery-operated Portable battery-powered instruments equipment. The power consumption is 1.5 mW at 5 V, 0.7 mW Digital gain and offset adjustment at 3 V, reducing to 1 W in power-down mode.
