TLV2542ID 

12-bit ADC with processing speeds up to 200ksps, with serial outputs, TMS320 compatible (up to 10MHz), dual-channel, and auto-sweep

illustrate   The TLV2541, TLV2542, and TLV2545 a high-performance, 12-bit, low-power, miniature, CMOS analog-to-digital converter (ADC) family. The TLV254x to 5.5 V power supply for home operations is from a single 2.7-V supply. The device is available with single, dual, or single pseudo-differential inputs. Each device has a chip selector (CS), serial clock (SCLK), serial data output (SDO), providing a direct three-wire interface to the interface) serial port of the most commonly used host microprocessor (SPI). When the TMS320™ interface is interfaced with a digital signal processor, a frame synchronization signal (FS can be used to represent a data frame TLV2541 start the sequence of CS for all devices or FS. TLV2541, the purpose of TLV2542 and TLV2545 is to use very low power consumption.   characteristic   Maximum throughput. . . 200 140 ksps Built-in conversion clock INL/DNL: ± 1 LSB max, Sin-Nab ratio: 72 dB, SFDR: 85 dB, female I = 20 kHz SPI/DSP compatible serial interface Single power supply: 2.7 volts to 5.5 volts The rail-to-rail and analog input bandwidth is 500 kHz Three options: TLV2541: Mono input TLV2542: With Autosweep dual channel TLV2545: Pseudo-differential input single channel Low-power Autopower downward Operating current: 2.7 volts at 1 mA, 1.5 mA at 5 V Autopower: 2.7 volts at 2μA, 5 microamps at 5 V Small 8-pin MSOP and SOIC packages
