ADS7804U/1K集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7804U/1K属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的ADS7804U/1K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 ADS7804 is a complete 12-bit sampling analog-to-digital

(A/D) converter using state-of-the-art CMOS structures. It

contains a complete 12-bit, capacitor-based, SAR A/D converter

with S/H, reference, clock, interface for microprocessor

use, and three-state output drivers.

The ADS7804 is specified at a 100kHz sampling rate, and

guaranteed over the full temperature range. Laser-trimmed

scaling resistors provide an industrystandard

±10V input range, while the innovative design

allows operation from a single +5V supply, with power

dissipation under 100mW.

The 28-pin ADS7804 is available in plastic 0.3 DIP and SO

packages, both fully specified for operation over the industrial

–40°C to +85°C range.
