Overview
The DAC7513N/3K, produced by Texas Instruments, is a low-power, single, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It features a versatile 3-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP interfaces, operating at clock rates up to 30MHz. The on-chip precision output amplifier allows for rail-to-rail output swing, making it suitable for a variety of applications. The DAC7513N/3K is designed for low-power consumption, making it ideal for portable battery-operated equipment, with a power consumption of 0.5mW at 5V and reducing to 1 µW in power-down mode.
