Texas Instruments TLV2543 12-Bit 66 kSPS ADC Ser. Out, Pgrmable Pwrdn, MSB/LSB First, Built-In Self-Test Mode, 11 Ch. TLV2543CDWG4

The TLV2543 is a 12-bit analog-to-digital converter (ADC) designed for high-speed data acquisition with a maximum sampling rate of 66 kSPS. It features 11 analog input channels, which are multiplexed, allowing for versatile input selection. The device incorporates a built-in self-test mode and supports both unipolar and bipolar output configurations. The TLV2543 operates with a programmable power-down feature, enabling energy efficiency during idle periods. It has a conversion time of 10 microseconds across its specified operating temperature range. The ADC utilizes a switched-capacitor design, ensuring low error rates and high linearity, with a maximum linearity error of ±1 LSB. Communication with the host processor is facilitated through a serial output, and the device includes an end-of-conversion (EOC) output signal to indicate when data is ready for transfer. The TLV2543 is available in multiple package types, including SOIC and PDIP, and is characterized for operation in two temperature ranges: 0°C to 70°C for the TLV2543C version and -40°C to 85°C for the TLV2543I version.
