Key Features
- Dual 8-bit DAC channels with 100 kSPS update rate and rail-to-rail output up to 2.5 V enable precise analog signal generation in compact embedded systems
- Integrated internal 2.5 V reference eliminates external reference circuitry, reducing BOM count and board area in cost-sensitive designs
- SPI-compatible 3-wire serial interface with 2.7 V to 5.5 V supply range simplifies interfacing to 3.3 V and 5 V microcontrollers without level shifters
Applications
The LTC2644CMS-L8#PBF is suited for generating analog control signals in portable instrumentation, industrial process control loops, and sensor calibration circuits requiring two independent 8-bit DAC outputs at up to 100 kSPS. Its internal 2.5 V reference and rail-to-rail output simplify design in battery-powered devices and handheld testers where supply voltage may vary between 2.7 V and 5.5 V. The MSOP-12 footprint supports high-density PCB layouts in space-constrained embedded control boards.

Frequently Asked Questions
How many DAC channels does the LTC2644CMS-L8#PBF provide and what is the maximum output voltage per channel?
The LTC2644CMS-L8#PBF provides 2 independent DAC channels, each with 8-bit resolution and a rail-to-rail output range up to 2.5 V when using the internal reference, enabling simultaneous control of two independent analog signals at update rates up to 100 kSPS.
Does the LTC2644CMS-L8#PBF include an internal voltage reference, and how does that affect the PCB design?
Yes, the LTC2644CMS-L8#PBF integrates an internal 2.5 V reference, removing the need for a discrete external reference component. This reduces the BOM by at least 1 part and frees up PCB space in MSOP-12 based designs while maintaining output accuracy with a typical linearity error below 0.2% (approximately ±0.5 LSB at 8 bits).
Which serial communication interface does the LTC2644CMS-L8#PBF use, and what supply voltage range is supported?
The LTC2644CMS-L8#PBF uses a 3-wire SPI-compatible serial interface supporting clock rates typical of standard SPI peripherals. The device operates from a 2.7 V to 5.5 V supply, making it directly compatible with 3.3 V microcontrollers such as ARM Cortex-M and 5 V AVR-based systems without requiring external level-shifting circuits.
