LTC2654BIGN-H16#PBF

Overview

The LTC2654BIGN-H16#PBF is a quad 16-bit voltage output digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It features an integrated precision reference with a maximum temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates from a single 4.5V to 5.5V supply and includes high-performance rail-to-rail output buffers guaranteed monotonic over temperature. Key electrical parameters include a maximum integral nonlinearity (INL) error of ±4 LSB, a maximum offset error of ±2 mV, and a settling time of 7.9 μs for 16-bit accuracy. Communication is handled via a 4-wire SPI/MICROWIRE compatible serial interface operating at clock rates up to 50 MHz.

Feature Summary

• Quad 16-bit resolution with integrated 10ppm/°C max precision reference
• Rail-to-rail output buffers with ultralow crosstalk (<3nV•s)
• Selectable internal or external reference modes
• Power-on-reset circuit configurable to zero-scale or mid-scale

Applications

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

Procurement Notes

Verify the package type matches the 16-lead narrow SSOP specification. Confirm the temperature grade corresponds to the Industrial range (-40°C to +85°C) indicated by the 'I' suffix. Ensure the lead finish is lead-free as denoted by the '#PBF' suffix. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm pinout and electrical characteristics.

Selection Notes

Select this component when four independent 16-bit DAC channels are required in a compact surface-mount package. The -H suffix indicates a 4.096V full-scale output requiring a 4.5V to 5.5V supply, suitable for applications needing higher voltage swings than the 2.5V option. The Industrial temperature grade ensures operation in harsh environments. Consider the external reference capability if system-level reference sharing is preferred over the internal source.

Part Context

This part belongs to the LTC2654 family of quad DACs, which also offers 12-bit resolution variants and different package options such as the 20-lead QFN. The 'B' designation specifies a maximum INL error of ±4 LSB at 16 bits, distinguishing it from standard accuracy parts. The 'GN' suffix identifies the specific 16-lead narrow SSOP physical footprint used in this ordering code.
