description
The TLV1543C, TLV1543I, and TLV1543M are
CMOS 10-bit, switched-capacitor, successive-
approximation, analog-to-digital converters.
These devices have three inputs and a 3-state
output [chip select (CS), input-output clock (I/O
CLOCK), address input (ADDRESS), and data
output (DATA OUT)] that provide a direct 4-wire
interface to the serial port of a host processor. The
devices allow high-speed data transfers from the
host.

In addition to a high-speed A /D converter and
versatile control capability, these devices have an
on-chip 14-channel multiplexer that can select
any one of 11 analog inputs or any one of three
internal self-test voltages. The sample-and-hold
function is automatic. At the end of A/D conversion, the end-of-conversion (EOC) output goes high to indicate
that conversion is complete. The converter incorporated in the devices 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 free-air
temperature range.
The TLV1543C is characterized for operation from 0°C to 70°C. The TLV1543I is characterized for industrial
temperature range of − 40°C to 85°C. The TLV1543M is characterized for operation over the full military
temperature range of −55°C to 125°C.
