The TLV2553-Q1 is a 12-bit switched-capacitor successive-approximation analog-to-digital
converter (ADC). 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 TLV2553-Q1 is characterized for operation from TA = 40°C to
