3 Description

The ADS9120 is an 16-bit, 2.5-MSPS, successive

approximation

register

(SAR)

analog-to-digital

converter (ADC) with ±0.25-LSB INL and 96-dB SNR

specifications under typical operating conditions. The

high throughput enables developers to oversample

the input signal to improve dynamic range and

accuracy of the measurement.

The device supports unipolar, fully-differential analog

input signals and operates with a 2.5-V to 5-V

external reference, offering a wide selection of input

ranges without additional input scaling.

The device consumes only 15.5 mW of power when

operating at the full 2.5-MSPS throughput. Power

consumption at lower throughputs can be reduced by

using the flexible low-power modes (NAP and PD).

The

integrated

multiSPI™

serial

interface

is

backward-compatible to the traditional SPI protocol.

Additionally, configurable features simplify board

layout,

timing,

and

firmware

and

achieve

high

throughput at lower clock speeds, thus allowing easy

interface with a variety of microcontrollers, digital

signal processors (DSPs), and field-programmable

gate arrays (FPGAs).

The device supports JESD8-7A compliant I/Os, the

extended industrial temperature range, and is offered

in a space-saving, 4-mm × 4-mm, VQFN package.
