ADC141S626

14-Bit, 50 kSPS to 250 kSPS, Differential Input, Micro Power

A/D Converter

General Description

Features

The ADC141S626 is a 14-bit, 50 kSPS to 250 kSPS sampling

Analog-to-Digital (A/D) converter. The converter is based on

a successive-approximation register architecture where the

differential nature of the analog inputs is maintained from the

internal track-and-hold circuits throughout the A/D converter

to provide excellent common-mode signal rejection. The

ADC141S626 features an external reference that can be var-

ied from 1.0V to V_Aand a zero-power track mode where the

ADC is consuming the minimum amount of supply current

while the internal sampling capacitor is tracking the applied

analog input voltage.

Interface

Key Specifications

The serial data output is binary 2's complement and is com-

patible with several standards, such as SPI™, QSPI™, MI-

CROWIRE™, and many common DSP serial interfaces. The

conversion result is clocked out by the serial clock input and

is the result of the conversion currently in progress.

The ADC141S626 may be operated with independent analog

(V_A) and digital input/output (V_IO) supplies. V_Aand V_IOcan

range from 2.7V to 5.5V and can be set independent of each

other. This allows a user to maximize performance and min-

imize power consumption by operating the analog portion of

the ADC at a V_Aof 5V while communicating with a 3V con-

troller on the digital side. Operating from a single 3V supply,

the power consumption when operating at 200 kSPS is 2.0

mW. While operating from a single 5V supply, the power con-

sumption when operating at 250 kSPS is 4.8 mW. The power

consumption drops down to 4 µW and 13 µW respectively

when the ADC141S626 enters acquisition mode. The differ-

ential input, low power consumption, and small size make the

ADC141S626 ideal for direct connection to bridge sensors

and transducers in battery operated systems or remote data

acquisition applications.
