TLV1572 说明

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 uA 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.

TLV1572 特性

• Fast Throughput Rate: 1.25 MSPS
• 8-Pin SOIC Package

• Integral Nonlinearity Error: < ±1 LSB
• Signal-to-Noise and Distortion Ratio: 59 dB, f(input) = 500 kHz
• Single 3-V to 5-V Supply Operation
• Very Low Power: 8 mW at 3V; 25mW at 5 V
• Auto-Powerdown: 10 uA Maximum
• Glueless Serial Interface to TMS320 DSPs and (Q)SPI Compatible Micro-Controllers
• Inherent Internal Sample and Hold Operation
