SGM71612R81/SGM71612R82/SGM71612R83

8 Channels, 16-Bit,

SPI Interface, Voltage-Output DAC

with 10ppm/℃ On-Chip Reference

GENERAL DESCRIPTION

FEATURES

The SGM71612R81/SGM71612R82/SGM71612R83

family is a 16-bit, 8 channels, voltage-output digital-to-

analog converter (DAC). These chips are guaranteed

monotonic by design.

● Power Supply Range: 2.7V to 5.5V

● On-Chip 1.25V/2.5V, 10ppm/℃ Reference

 SGM71612R81Z: 1.25V

 SGM71612R82Z/SGM71612R82M/SGM71612R83M:

2.5V

The SGM71612R81Z has an on-chip 1.25V 10ppm/℃

reference, giving a full-scale output range of 2.5V. The

SGM71612R82Z/SGM71612R82M/SGM71612R83M

have an on-chip 2.5V 10ppm/℃ reference, giving a

full-scale output range of 5V.

● Power Down to 500nA (TYP) at 5V, 300nA (TYP) at 3V

● Monotonicity Guaranteed by Design

● Power-On Reset to Zero-Scale or Mid-Scale

 SGM71612R81Z/SGM71612R82Z:

Power-On Reset to Zero

The chips have a power-on control circuit, which can

ensure that DAC has a fixed output when the system is

powered on. The SGM71612R81Z and SGM71612R82Z

output 0V when the system is powered up, and the

SGM71612R82M/SGM71612R83M outputs mid-scale

when the system is powered up.

 SGM71612R82M/SGM71612R83M:

Power-On Reset to Mid-Scale

● 3 Power-Down Modes

● Hardware nLDAC and nLDAC Override Function

● nCLR Function to Programmable Code

● Rail-to-Rail Buffered Voltage-Output Operation

● Available in Green TSSOP-16, TQFN-4×4-16BL

and FOCSP-2.6×2.6-16B Packages

The chips have an nLDAC pin that allows the DAC to

update the output simultaneously. And the chips have

an nCLR pin that allows the DAC to be updated to a

configurable state, zero-code, mid-scale, or full-scale.

APPLICATIONS

The SGM71612R81/SGM71612R82/SGM71612R83

family uses a 3-wire SPI-compatible interface, and its

operation data rate is up to 50MHz.

The SGM71612R81Z and SGM71612R82Z are

available in Green TSSOP-16, TQFN-4×4-16BL and

FOCSP-2.6×2.6-16B packages. The SGM71612R82M

and SGM71612R83M are available in Green

TSSOP-16 and TQFN-4×4-16BL packages.
