TLV1572集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLV1572属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLV1572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 TLV1572 is a high-speed 10-bit successive-approximation analog-to-digital converter (ADC) that operates

from a single 2.7-V to 5.5-V power supply and is housed in a small 8-pin SOIC package.

The TLV1572 accepts an analog input range from 0 to VCC and digitizes the input at a maximum 1.25 MSPS

throughput rate. The power dissipation is only 8 mW with a 3-V supply or 25 mW with a 5-V supply. The device

features an auto-powerdown mode that automatically powers down to 10 μA whenever a conversion is not

performed.

The TLV1572 communicates with digital microprocessors via a simple 3- or 4-wire serial port that interfaces

directly to the Texas Instruments TMS320 DSPs and (Q)SPI compatible microcontrollers without using

additional glue logic.

Very high throughput rate, simple serial interface, SO-8 package, 3-V operation, and low power consumption

make the TLV1572 an ideal choice for compact or remote high-speed systems.
