TLV2556-EP 具有内部参考的增强型产品 12 位 200KSPS 11 通道低功耗串行 ADC

The TLV2556 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.
