This schematic block features the LTC1661, a precision low-power dual 10-bit voltage-output DAC from Analog Devices’ Linear Technology line. Engineered for compact, high-performance analog control applications, the LTC1661 integrates two rail-to-rail output buffers, a fast 3-wire serial interface, and exceptionally low supply current—making it ideal for battery-operated and space-constrained designs.
Offered in a tiny 8-MSOP package, this breakout-style module exposes both DAC outputs, the serial data interface, and power pins in a clean layout optimized for quick testing and integration. Its low glitch energy, low offset error, and deterministic command structure enable stable, predictable analog control without extensive calibration overhead.
The LTC16xx family is widely used in instrumentation, automation, and portable systems due to its long production life, dependable performance, and Linear Technology’s legacy of robust precision analog components.
