- Compact 8-pin TSOT-23 package (2.9 mm × 1.6 mm) minimizes PCB footprint for space-constrained designs
What is LTC2640ITS8-LM12#TRMPBF used for?
The LTC2640ITS8-LM12#TRMPBF is used in precision analog control applications including programmable power supplies, sensor calibration, and industrial process control where 12-bit DAC resolution is required on a single SPI interface. Its 2.7 V to 5.5 V supply range makes it suitable for battery-powered instrumentation, wearable sensors, and portable medical devices where supply voltage varies with state of charge. The compact TSOT-23 package and internal reference enable single-chip DAC solutions in space-constrained embedded systems with 3.3 V or 5 V microcontroller interfaces.

Frequently Asked Questions
What resolution and interface does the LTC2640ITS8-LM12#TRMPBF DAC use?
The LTC2640ITS8-LM12#TRMPBF provides 12-bit resolution over a serial SPI interface with binary-coded input format. This gives 4096 discrete output levels across the output voltage range of 0 V to 2.5 V, yielding a step size of approximately 0.61 mV per LSB, which is suitable for precision control loops and analog set-point generation in industrial instruments.
What is the linearity error specification of the LTC2640ITS8-LM12#TRMPBF and why does it matter?
The LTC2640ITS8-LM12#TRMPBF specifies a maximum integral nonlinearity (INL) of 0.061%, which corresponds to approximately ±2.5 LSB error at 12-bit resolution. For precision analog output in sensor calibration or closed-loop control, low INL ensures the DAC output accurately tracks the digital code across the full 0 V to 2.5 V range without cumulative step-size errors degrading system accuracy.
How does the 2.7 V to 5.5 V supply range of the LTC2640ITS8-LM12#TRMPBF benefit battery-operated designs?
The 2.7 V to 5.5 V supply range allows the LTC2640ITS8-LM12#TRMPBF to operate across a LiPo cell's full discharge curve from 4.2 V down to 2.7 V without a boost converter. In portable and wearable devices, this eliminates the need for a regulated 3.3 V rail solely for the DAC, reducing BOM cost and quiescent power draw in battery-powered data loggers and field instruments.
When is the LTC2640ITS8-LM12#TRMPBF a better choice than a 10-bit SPI DAC for an analog control application?
In analog control applications requiring output voltage accuracy below 2 mV on a 2.5 V scale, the 12-bit LTC2640 provides 0.61 mV per LSB versus approximately 2.4 mV per LSB for a 10-bit DAC — a 4× improvement in resolution. For PID controllers managing temperatures to ±0.5°C or pressure regulators targeting ±0.1% accuracy, this extra 2 bits reduces quantization error enough to eliminate the need for gain-scaling stages in the analog output path.
