Product Summary
The AD53025JSTP is a buffered voltage output DAC in a 10-lead mSOIC package that operate from a single +2.5 V to +5.5 V supply consuming 230 mA at 3 V. The references for the two DACs are derived from two reference pins (one per DAC). The reference inputs may be configured as buffered or unbuffered inputs. The outputs of the AD53025JSTP may be updated simultaneously using the asynchronous LDAC input. The parts incorporate a power-on-reset circuit that ensures that the DAC outputs power-up to 0 V and remain there until a valid write takes place to the device. The AD53025JSTP contains a powerdown feature that reduces the current consumption of the devices to 200 nA at 5 V (50 nA at 3 V) and provides softwareselectable output loads while in power-down mode. Applications are (1)Portable Battery-Powered Instruments; (2)Digital Gain and Offset Adjustment; (3)Programmable Voltage and Current Sources; (4)Programmable Attenuators.
