LTC2624IGN#PBF

Overview

The LTC2624IGN#PBF is a quad 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It operates from a single 2.5V to 5.5V supply and features separate reference inputs for each channel. The device utilizes an SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical specifications include a settling time of 7µs, ±0.5 LSB differential nonlinearity, and ±0.9 LSB integral nonlinearity. Supply current is typically 1.3mA at 5V. The part supports individual power-down modes and includes a hardware clear function.

Feature Summary

• Quad 12-bit resolution with rail-to-rail voltage outputs
• Separate reference inputs for each DAC channel
• SPI/MICROWIRE compatible 3-wire serial interface
• Ultralow crosstalk between DACs (<5µV)

Applications

• Mobile communications
• Process control and industrial automation
• Instrumentation
• Automatic test equipment

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation. The provided datasheet lists 'LTC2624IGN#PBF' as a valid part number variant within the family. Confirm that the '#PBF' suffix denotes lead-free finish and tape/reel or tube packaging requirements as specified in the official order information table. Cross-reference the exact part marking code '2624I' to ensure authenticity.

Selection Notes

Select this component when four independent 12-bit voltage outputs are required in a compact 16-lead SSOP footprint. It is suitable for applications needing separate reference inputs per channel and low crosstalk performance. Compare against LTC2604 (16-bit) or LTC2614 (14-bit) if higher resolution is needed, or consider the -1 variants if mid-scale power-on reset behavior is preferred over zero-scale.

Part Context

This component belongs to the LTC2604/LTC2614/LTC2624 family of quad DACs. They share identical pinouts, package types, and interface protocols, differing primarily in resolution (16, 14, and 12 bits respectively). The IGN suffix indicates an industrial temperature range (-40°C to +85°C), while the CGN suffix denotes a commercial range (0°C to 70°C). All variants offer guaranteed monotonicity and similar power characteristics.

Replacement Considerations

Direct pin-compatible substitutes within the same family include LTC2604IGN#PBF (16-bit) and LTC2614IGN#PBF (14-bit). For lower resolution needs, LTC2624CGN#PBF offers the same functionality in a commercial temperature grade. Ensure software compatibility with the 12-bit data word structure (12 data bits + 4 don't-care bits) when replacing other resolutions.
