DESCRIPTION
The
TLV2553
is
a
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.
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.
The TLV2553I is characterized for operation from
TA = –40°C to 85°C. See available options table for
package options.
