Overview
The LTC2620IGN#TRPBF is an octal 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates within a wide supply voltage range of 2.5V to 5.5V and features built-in high-performance output buffers guaranteed monotonic over temperature. The device utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface capable of clock rates up to 50MHz, including daisychain capability and a hardware clear function. Packaged in a 16-lead narrow SSOP, it offers low power consumption of 250μA per DAC at 3V and individual channel power-down down to 1μA.
Feature Summary
- Octal 12-Bit Rail-to-Rail Voltage Output with Built-in Buffers
- SPI/MICROWIRE Compatible 3-Wire Serial Interface (Up to 50MHz)
- Low Power: 250μA per DAC at 3V; Individual Channel Power-Down to 1μA
- 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 specific ordering suffix #TRPBF indicates tape and reel packaging for automated assembly. Confirm the IGN suffix corresponds to the industrial temperature range (-40°C to +85°C) and the 16-lead SSOP package. Ensure compatibility with existing inventory specifications regarding lead-free finish and RoHS compliance status.
Selection Notes
Select this component when eight independent 12-bit voltage outputs are required in a compact 16-lead SSOP footprint. It is suitable for applications demanding low crosstalk and high drive current from a single supply. Consider the LTC2600 or LTC2610 if higher resolution (16-bit or 14-bit) is needed, as they share pinouts and interfaces.
Part Context
This part belongs to the LTC2600/LTC2610/LTC2620 family of octal DACs. These devices are designed to establish board-density benchmarks for multi-channel conversion. The family includes pin-compatible versions with varying resolutions, allowing designers to scale performance without changing the PCB layout significantly.
Replacement Considerations
Pin-compatible alternatives within the same package include the LTC2600 (16-bit) and LTC2610 (14-bit). For lower resolution requirements, the LTC1660 (10-bit) and LTC1665 (8-bit) offer similar form factors.
