TLV2553IDW

АЦП, 12 бит, 200 Квыборок/с, Однополярный, 2.7 В, 5.5 В, SOIC.

The TLV2553IDW is a 12-bit successive-approximation Analog-to-digital Converter (ADC) has three control inputs [chip select (CS), the input-output clock and the address/control input. The switched-capacitor ADC is 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.
