- TIPD129, 0-1A, Single-Supply, Low-Side, Current Sensing Solution. This Verified Design implements a single-supply, low-side current sensing solution that can accurately detect load current from 0-1A. The corresponding linear output range is from 0V to 4.9V. This design relies on the LM7705 inverting charge pump to bias the negative supply of the OPA320 to -0.23V. This setup extends the linear output range of the amplifier below 0V. The circuit's linear operation across the entire 0-1A input range enables calibrated performance to within 0.003% error
