Product Introduction

Overview

The DAC7512E/250G4, produced by Texas Instruments, is a low-power, single, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It features an on-chip precision output amplifier that enables rail-to-rail output swing, making it suitable for a wide range of applications. The DAC7512 uses a versatile three-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP interfaces, operating at clock rates up to 30MHz. The device is designed for low power consumption, making it ideal for portable battery-operated equipment.
