TLV1572集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

TLV1572屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由美國德州儀器公司制造生產(chǎn)的TLV1572模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。

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.
