Product Overview
DAC60508ZRTER from TI is an 8-channel 12-bit voltage-output DAC with internal 2.5V reference (+/-0.2%). SPI up to 50MHz. Per-channel power-down. LDAC enables simultaneous channel updates. Compact VQFN-16 package.
Working Principle
Resistor-string DAC architecture. SPI writes to input registers. LDAC transfers all to DAC registers simultaneously. Each channel has output buffer. Internal 2.5V ref or external override. Power-down: 1uA per channel.
