LTC6912IGN-1#TRPBF

Overview

The LTC6912IGN-1#TRPBF is a dual-channel, low-noise, digitally programmable gain amplifier (PGA) from Analog Devices. It features independent gain control via a 3-wire SPI interface for each channel. The LTC6912-1 variant supports voltage gains of 0, 1, 2, 5, 10, 20, 50, and 100V/V. All gains are inverting. The device operates on single or split supplies ranging from 2.7V to 10.5V total. It utilizes a 16-lead narrow SSOP package.

Feature Summary

• Dual channels with independent digital gain programming via 3-wire SPI
• Rail-to-rail input range and rail-to-rail output swing capabilities
• Internal half-supply reference at AGND pin for single supply operation
• Low power hardware shutdown mode available for the GN package

Applications

• Data acquisition systems
• Dynamic gain changing circuits
• Automatic ranging circuits
• Automatic gain control applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the IGN designation corresponds to the industrial temperature grade (-40°C to 85°C). Ensure the -1 suffix matches the required gain settings (0 to 100V/V) for your design requirements before procurement.

Selection Notes

Select the LTC6912IGN-1#TRPBF when dual-channel signal conditioning with precise digital gain steps is required. The industrial grade ensures functionality across a wide temperature range. Consider the inverting nature of all gain stages during system architecture planning. Verify that the 16-lead SSOP package fits the PCB layout constraints.

Part Context

This component belongs to the LTC6912 family of dual programmable gain amplifiers. The IGN-1 suffix specifies the industrial temperature range and the specific gain ladder configuration. The part integrates two matched amplifiers into a compact form factor suitable for space-constrained embedded designs requiring high precision.

Replacement Considerations

LTC6912CGN-1#TRPBF offers the same electrical characteristics but is specified for commercial temperature ranges. LTC6912HGN-1#TRPBF provides extended temperature performance up to 125°C. Both variants maintain identical pinouts and functional specifications.
