GENERAL DESCRIPTION

purposes. Data readback allows the user to read the contents of

the DAC register via the SDO pin.

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

that operates from supply voltages of 1ꢀ V up to 15 V.

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

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

are changing), V_OUTis clamped to 0 V via a low impedance path.

LDAC

Features on the AD5570 include

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

power state, and a

pin that allows the output to be cleared

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 is available in a 16-lead SSOP package.

PRODUCT HIGHLIGHTS

1. 1 LSB maximum INL and DNL.

ꢀ. Buffered voltage output up to 1ꢁ V.

3. Output controlled during power-up.

ꢁ. On-board reference buffers.

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 in the format of a 16-bit serial

word. Serial data is available on the SDO pin for daisy-chaining

5. Wide temperature range of −ꢁ0°C to +1ꢀ5°C.
