Low-Cost Digitally Programmable Gain Amplifier Reference Design
Description
This simple and low-cost digitally programmable gain amplifier design creates non-inverting gains ranging from 6dB (2V/V) to 60dB (1000V/V). The design is based on a general purpose op amp and a digital potentiometer as one of the gain-setting elements. The digital potentiometer is controlled with a standard I2C digital interface.
Features
- Digital Programmed Gain Range: 6dB - 60dB (2V/V - 1000V/V)Controlled with I2C Digital CommandsFeatures Non-Voltatile EEPROM memoryPower Supply Voltage ±2.7 V to ±5.5 VVerified reference design includes theory: calculated error analysis: component selection: PCB layout: and measured results
