TLV1549IDG4集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLV1549IDG4属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLV1549IDG4模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

description

The TLV1549C, TLV1549I, and TLV1549M are

10-bit, switched-capacitor, successiveapproximation,

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 lowerror

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.
