AD5317: 4 buffered 10-bit DACs in 16-lead TSSOP

A version: 4 ꢀSB INꢀ; B version: 2.5 ꢀSB INꢀ

AD5327: 4 buffered 12-bit DACs in 16-lead TSSOP

A version: 16 ꢀSB INꢀ; B version: 10 ꢀSB INꢀ

ꢀow power operation: 400 μA @ 3 V, 500 μA @ 5 V

2.5 V to 5.5 V power supply

The AD5307/AD5317/AD5327¹are 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.

Guaranteed monotonic by design over all codes

ꢀDAC

Power down to 90 nA @ 3 V, 300 nA @ 5 V (

Double-buffered input logic

pin)

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.

Buffered/unbuffered reference input options

Output range: 0 V to V_REFor 0 V to 2 V_REF

Power-on reset to 0 V

ꢀDAC

Simultaneous update of outputs (

CꢀR

pin)

CLR

Asynchronous clear facility (

pin)

There is also an asynchronous active low

DACs to 0 V. The outputs of all DACs can be updated simul-

LDAC

pin that clears all

ꢀow power, SPI®-, QSPI™-, MICROWIRE™-, and DSP-

compatible 3-wire serial interface

SDO daisy-chaining option

On-chip rail-to-rail output buffer amplifiers

Temperature range of −40°C to +105°C

taneously using the asynchronous

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.

APPꢀICATIONS

Portable battery-powered instruments

Digital gain and offset adjustment

Programmable voltage and current sources

Programmable attenuators

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.
