LTC2620CUFD#PBF

Overview

The LTC2620CUFD#PBF is an octal 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) in a 20-lead 4mm × 5mm QFN package. It operates on a single 2.5V to 5.5V supply and features built-in high-performance output buffers capable of sourcing or sinking at least 15mA. The device utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include guaranteed monotonicity, ultralow crosstalk (<10μV), and low power consumption of 250μA per DAC at 3V. Individual channels can be powered down to 1μA maximum.

Feature Summary

Octal 12-bit resolution with rail-to-rail voltage outputs
SPI/MICROWIRE compatible 3-wire serial interface supporting 50MHz clock
Guaranteed 12-bit monotonic operation over temperature
Ultralow crosstalk between DACs (<10μV) and high drive capability (±15mA min)

Applications

Mobile Communications
Process Control and Industrial Automation
Instrumentation
Automatic Test Equipment

Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tape and reel availability if required. Confirm the 'C' grade corresponds to the 0°C to 70°C commercial temperature range. Ensure the UFD package designation matches the 20-lead 4mm × 5mm Plastic DFN form factor specified in the order information table.

Selection Notes

Select this component when eight independent 12-bit voltage outputs are required in a compact footprint. The LTC2620 offers pin compatibility with 16-bit (LTC2600) and 14-bit (LTC2610) variants within the same family. Consider the 2.5V to 5.5V supply range and the need for daisy-chain capability via the SDO pin for system integration.

Part Context

This part belongs to the LTC2600/LTC2610/LTC2620 family of octal DACs. While the LTC2600 provides 16-bit resolution and the LTC2610 provides 14-bit resolution, the LTC2620 specifically delivers 12-bit accuracy. All three share identical pinouts, interfaces, and package options, allowing for design flexibility across different precision requirements without changing the board layout.

Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2600CUFD#PBF (16-bit) and LTC2610CUFD#PBF (14-bit). For lower resolution needs, the LTC1660 and LTC1665 are also pin-compatible 8-bit and 10-bit versions.
