GENERAL DESCRIPTION

The AD5570 is a single 16-bit serial input, voltage output DAC

that operates from supply voltages of ±11.4 V up to ±16.5 V.

Integral linearity (INL) and differential nonlinearity (DNL) are

accurate to 1 LSB. During power-up, when the supply voltages

are changing, V

OUT

is clamped to 0 V via a low impedance path.

The AD5570 DAC comes complete with a set of reference

buffers. The reference buffers allow a single, positive reference

to be used. The voltage on REFIN is gained up and inverted

internally to give the positive and negative reference for the

DAC core. Having the reference buffers on-chip eliminates the

need for external components such as inverters, precision

amplifiers, and resistors, thereby reducing the overall solution

size and cost.

The AD5570 uses a versatile 3-wire interface that is compatible

with SPI®, QSPI™, MICROWIRE™, and DSP® interface standards.

Data is presented to the part as a 16-bit serial word. Serial data

is available on the SDO pin for daisy-chaining purposes. Data

readback allows the user to read the contents of the DAC

Features on the AD5570 include LDAC which is used to update

the output of the DAC. The device also has a power-down pin

(PD), allowing the DAC to be put into a low power state, and a

CLR pin that allows the output to be cleared to 0 V.

The AD5570 is available in a 16-lead SSOP.

PRODUCT HIGHLIGHTS

1 LSB maximum INL and DNL.

Buffered voltage output up to ±14 V.

Output controlled during power-up.

On-board reference buffers.

Wide temperature range of

−40°C

to +125°C.

5 kV HBM ESD classification.
