TLV1549中文资料10 位 38kSPS ADC，串行输出、固有采样保持、终端与 TLC1549 和 TLC1549x 兼容数据手册TI规格书

描述 Description

The TLV1549C, TLV1549I, and TLV1549M are 10-bit, switched-capacitor, successive-approximation, analog-to-digital converters. The devices have two digital inputs and a 3-state output [chip select (CS\\), input-output clock (I/O CLOCK), and data output (DATA OUT)] that provide a three-wire interface to the serial port of a host processor. The sample-and-hold function is automatic. 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. A switched-capacitor design allows low-error conversion over the full operating free-air temperature range. The TLV1549C is characterized for operation from 0°C to 70°C. The TLV1549I is characterized for operation from -40°C to 85°C. The TLV1549M is characterized for operation over the full military temperature range of -55°C to 125°C.
