Description

The LTC1668IG#PBF is a 10-bit, dual-channel digital-to-analog converter (DAC) from Analog Devices. It operates with a single 3V to 5.5V supply, making it suitable for low-power applications.
Key features:
- 10-bit resolution with rail-to-rail output.
- Dual DACs in one package, each with independent references.
- SPI-compatible serial interface for easy microcontroller interfacing.
- Low power consumption (0.7mW typical at 3V).
- Fast settling time (4µs typical).
Applications include programmable voltage sources, industrial control, and instrumentation. The IG#PBF suffix indicates a lead-free, 28-pin SSOP package.
For detailed specs, refer to the datasheet.
