LTC2654BCGN-H16#PBF

Overview

The LTC2654BCGN-H16#PBF is a quad 16-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It features an integrated reference providing a full-scale output of 4.096V, requiring a supply voltage between 4.5V and 5.5V. The device includes rail-to-rail output buffers and guarantees monotonicity over temperature. Key electrical specifications include a maximum integral nonlinearity (INL) of ±4 LSB, a settling time of 7.9µs to ±1 LSB at 16 bits, and a power supply rejection ratio of -80 dB. It communicates via a 4-wire SPI/Microwire compatible interface with clock rates up to 50MHz.

Feature Summary

• Quad 16-bit resolution with integrated 4.096V reference
• Maximum INL error of ±4 LSB and offset error of ±2 mV
• Ultralow crosstalk between DACs (<3nV•s)
• Power-on reset selectable to zero-scale or mid-scale

Applications

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

Procurement Notes

Verify the specific ordering suffix 'H16' corresponds to the 4.096V full-scale range and 4.5V-5.5V supply requirement. Confirm the 'B' grade indicates the ±4 LSB maximum INL specification. Ensure the GN package denotes the 16-lead narrow SSOP form factor suitable for surface mount assembly.

Selection Notes

Select this part when a quad-channel configuration with high precision (16-bit) and a fixed 4.096V output span is required. The H-option necessitates a minimum 4.5V supply, distinguishing it from L-options that operate down to 2.7V. Consider the ±4 LSB INL grade if tighter linearity is not critical, as C-grade parts offer ±1 LSB INL.

Part Context

This component belongs to the LTC2654 family of rail-to-rail DACs. The BC prefix identifies the commercial temperature grade (0°C to 70°C) and the B accuracy grade. The GN suffix specifies the 16-lead narrow SSOP package, while H16 defines the 4.096V internal reference and 16-bit resolution.
