TLA2528集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLA2528属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLA2528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。

3 Description

The TLA2528 is an easy-to-use, 8-channel,

multiplexed, 12-bit, successive approximation register

analog-to-digital converter (SAR ADC). The eight

channels can be independently configured as either

analog inputs, digital inputs, or digital outputs. The

device has an internal oscillator for ADC conversion

processes.

The TLA2528 communicates via an I2C-compatible

interface and supports standard-mode (100 kHz),

fast-mode (400 kHz), fast-mode plus (1 MHz), and

high-speed mode (3.4 MHz). Up to eight I2C

addresses can be selected for the TLA2528 by

connecting a resistor on the ADDR pin.
