GENERAL DESCRIPTION
The AD5307/AD5317/AD53271 are quad 8-,10-,12-bit buffered
voltage-output DACs in 16-lead TSSOP that operate from single
2.5 V to 5.5 V supplies and consume 400 μA at 3 V. Their on-
chip output amplifiers allow the outputs to swing rail-to-rail with
a slew rate of 0.7 V/μs. The AD5307/AD5317/AD5327 utilize
versatile 3-wire serial interfaces that operate at clock rates up to
30 MHz; these parts are compatible with standard SPI, QSPI,
MICROWIRE, and DSP interface standards.
The references for the four DACs are derived from two reference
pins (one per DAC pair). These reference inputs can be configured
as buffered or unbuffered inputs. Each part incorporates a power-
on reset circuit, ensuring that the DAC outputs power up to 0 V
and remain there until a valid write to the device takes place.
There is also an asynchronous active low CLR pin that clears all
DACs to 0 V. The outputs of all DACs can be updated simul-
taneously using the asynchronous LDAC input. Each part
contains a power-down feature that reduces the current
consumption of the device to 300 nA @ 5 V (90 nA @ 3 V). The
parts can also be used in daisy-chaining applications using the
SDO pin.
All three parts are offered in the same pinout, allowing users to
select the amount of resolution appropriate for their application
without redesigning their circuit board.
