TLV2556MPWREP

TLV2556MPWREP Description

The TLV2556MPWREP from Texas Instruments is a high-performance 12-bit SAR (Successive Approximation Register) ADC designed for precision analog-to-digital conversion in embedded systems. This surface-mount device, packaged in a 20-pin TSSOP with tape-and-reel (TR) delivery, operates with a single-ended input configuration and supports 11 input channels. It features a 200kSPS sampling rate, making it ideal for applications requiring moderate-speed, high-resolution data acquisition. The ADC operates across a wide analog/digital supply range (2.7V to 5.5V), ensuring compatibility with both 3.3V and 5V systems. Its SPI interface simplifies integration with microcontrollers and DSPs, while external/internal reference options enhance flexibility in design.
