TLV2553

SLAS354B – SEPTEMBER 2001 – REVISED SEPTEMBER 2002

12-BIT, 200-KSPS, 11-CHANNEL, LOW-POWER, SERIAL ADC

In addition to the high-speed converter and versatile

control capability, the device has an on-chip 14-channel

multiplexer that can select any one of 11 inputs or any

one of three internal self-test voltages using

configuration register 1. The sample-and-hold function

is automatic. At the end of conversion, when

programmed as EOC, the pin 19 output goes high to

indicate that conversion is complete. The converter

incorporated in the device features differential, high-

impedance reference inputs that facilitate ratiometric

conversion, scaling, and isolation of analog circuitry

from logic and supply noise. A switched-capacitor

design allows low-error conversion over the full

operating temperature range.

AIN10

AIN9

The TLV2553 is

12-bit, switched-capacitor,

successive-approximation, analog-to-digital converter.

The ADC has three control inputs [chip select (CS), the

input-output clock, and the address/control input

(DATAIN)], designed for communication with the serial

port of a host processor or peripheral through a serial

3-state output.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
