ADS7805U/1K集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7805U/1K属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS7805U/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 ADS7805 is a complete 16-bit sampling, Analog-to-

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

It contains a complete 16-bit, capacitor-based, Successive

Approximation Register (SAR) A/D converter with

Sample-and-Hold (S/H), reference, clock, interface for microprocessor

use, and 3-state output drivers.

The ADS7805 is specified at a 100kHz sampling rate and

ensured over the full temperature range. Laser-trimmed

scaling resistors provide an industry-standard ±10V input

range while the innovative design allows operation from a

single +5V supply, with power dissipation under 100mW.

The ADS7805 is available in a 0.3 DIP-28 and an SO-28

package. Both are fully specified for operation over the

industrial –25°C to +85°C range; however, they will function

over the –40°C to +85C temperature range.
