Key Features
- 8 selectable gain steps from -1V/V to +32V/V per channel controlled via 3-wire SPI, enabling software-programmable signal conditioning without mechanical potentiometers
- Dual independent channels in one 16-pin SSOP package reduces board area and component count in stereo or differential-path amplifier chains
- Gain-bandwidth product exceeding 100MHz maintains signal integrity in high-frequency analog signal chains up to several tens of MHz
- Low noise and low distortion characteristics preserve ADC dynamic range in precision measurement and audio test equipment applications
- ±5V dual supply operation is directly compatible with standard bipolar analog power rails used in industrial and instrumentation equipment
Applications
The LTC6912CGN-1#PBF is used in programmable signal conditioning front ends for data acquisition systems where gain must be adjusted dynamically by firmware to accommodate wide input signal ranges without manual calibration. It suits audio test and measurement equipment requiring software-selectable gain in both channels simultaneously via SPI, enabling automated frequency response sweeps and distortion analysis. Medical instrumentation designers apply it in biopotential amplifier chains where the ability to step gain in discrete calibrated increments of 2x, 4x, 8x, and 16x from a microcontroller reduces analog circuit complexity.

Frequently Asked Questions
How many gain settings does the LTC6912CGN-1#PBF offer, and what is the gain range across those settings?
The LTC6912CGN-1#PBF provides 8 digitally selectable gain settings ranging from -1 V/V (inverting unity gain) up to +32 V/V in discrete steps of 0, 1, 2, 4, 8, 16, and 32 V/V per channel. This 35dB programmable gain range allows a single PGA to replace multiple switched fixed-gain stages in precision measurement front ends, reducing component count and eliminating relay or analog switch glitches during gain transitions.
What SPI clock speed does the LTC6912CGN-1#PBF accept, and how quickly can gain be updated between measurements?
The LTC6912CGN-1#PBF accepts SPI clock rates up to 25MHz for gain word loading. At this rate, a 16-bit gain update transaction completes in under 1µs, allowing a microcontroller or FPGA to reprogram both channel gains between consecutive ADC conversions in a high-speed multiplexed data acquisition system sampling at up to 500kHz without timing budget violations.
For a dual-channel audio analyzer, can the LTC6912CGN-1#PBF handle audio-band signals without significant noise or distortion?
Yes, the LTC6912CGN-1#PBF is designed for precision analog signal chains with low input-referred noise and low harmonic distortion across audio frequencies from 20Hz to 20kHz. At unity gain, the device maintains a signal-to-noise ratio compatible with 16-bit to 18-bit ADC dynamic range, making it suitable for THD+N measurements, frequency response sweeps, and signal generator level control in bench-top and automated audio test equipment.
Is the LTC6912CGN-1#PBF RoHS compliant, and what does the PBF suffix indicate for procurement?
The PBF suffix on LTC6912CGN-1#PBF indicates that this ordering variant is lead-free (Pb-Free), using a matte tin (Sn) terminal finish compatible with RoHS Directive 2011/65/EU and REACH requirements. The base part LTC6912CGN-1 without the PBF suffix uses a tin-lead finish and is not RoHS compliant. Designers targeting EU market products or RoHS-compliant supply chains must specify the #PBF variant to avoid regulatory non-compliance during final product certification.
