The TLV1543C 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 TLV1543M is characterized for operation
over the full military temperature range of – 55°C to 125°C.
