Overview
The LTC2620IGN#PBF is an octal 12-bit rail-to-rail voltage-output digital-to-analog converter (DAC) housed in a 16-lead narrow SSOP package. It operates on a single supply voltage ranging from 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. Power consumption is low at 250μA per DAC at 3V, with individual channel power-down reducing current to 1μA maximum.
Feature Summary
- Octal 12-bit resolution with rail-to-rail voltage outputs
- SPI/MICROWIRE compatible 3-wire serial interface with 50MHz clock rate
- Guaranteed 16-bit monotonicity over the full operating temperature range
- Low power operation: 250μA per DAC at 3V; individual channel power-down to 1μA max
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Instrumentation
- Automatic Test Equipment
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm the presence of the Linear Technology logo and lead-free marking on the shipping container. Check for RoHS compliance documentation. Ensure the part number matches the specific order information table for the 16-lead Plastic SSOP package variant.
Selection Notes
Select this model for applications requiring eight independent 12-bit voltage outputs in a compact 16-lead SSOP footprint. It is suitable where board density is critical compared to higher bit-count variants like the LTC2600 or LTC2610. Ensure the system requires a 2.5V to 5.5V supply range and SPI-compatible digital interface. Consider the -40°C to 85°C industrial temperature range specified for the 'I' grade suffix.
Part Context
This component belongs to the LTC2600/LTC2610/LTC2620 family of octal DACs. The LTC2620 specifically provides 12-bit resolution, whereas the LTC2600 offers 16 bits and the LTC2610 offers 14 bits. All three share pin compatibility and identical package options, allowing for design flexibility across different resolution requirements within the same form factor.
Replacement Considerations
Pin-compatible alternatives within the same series include the LTC2600IGN#PBF (16-bit) and LTC2610IGN#PBF (14-bit). Lower resolution versions such as the LTC1660 or LTC1665 are also pin-compatible but offer 10-bit and 8-bit resolutions respectively.
