LTC2620CGN#PBF

Overview

The LTC2620CGN#PBF is an octal 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.5V to 5.5V and features built-in high-performance output buffers. The device utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface capable of clock rates up to 50MHz. Key electrical specifications include a maximum differential nonlinearity (DNL) of ±0.5 LSB, integral nonlinearity (INL) of ±0.75 LSB, and a typical settling time of 7µs. Each channel supports a minimum rail-to-rail output drive current of ±15mA.

Feature Summary

• Octal architecture with 8 independent 12-bit DAC channels in a 16-lead narrow SSOP package
• Guaranteed monotonic operation over the full operating temperature range
• Ultralow crosstalk between DAC channels, specified at less than 10µV
• Individual channel power-down capability reducing current consumption to a maximum of 1µA

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Instrumentation
• Automatic Test Equipment

Procurement Notes

Verify that the component matches the specific 'C' grade temperature rating of 0°C to 70°C. Confirm the package type is the 16-lead Plastic SSOP. Ensure the ordering suffix '#PBF' indicates lead-free finish compliance. Check for availability of the tape and reel variant if automated surface-mount assembly is required.

Selection Notes

Select this model when eight simultaneous analog outputs are required within a compact footprint. The 12-bit resolution is suitable for applications where lower precision allows for reduced power consumption compared to the 14-bit or 16-bit variants. Verify that the system logic levels are compatible with the specified digital input voltage ranges for the chosen supply voltage.

Part Context

This component belongs to the LTC2600/LTC2610/LTC2620 family of octal DACs. It shares pin compatibility and interface protocols with the 16-bit LTC2600 and 14-bit LTC2610 models. The family is designed to establish board-density benchmarks for multi-channel voltage-output converters in single-supply systems.

Replacement Considerations

Pin-compatible alternatives within the same package include the LTC2600CGN#PBF for higher resolution and the LTC2610CGN#PBF for intermediate resolution. Lower bit-count versions such as the LTC1660 or LTC1665 may also serve as substitutes if fewer channels or lower precision are acceptable.
