Improved isolation amplifier transmits dc or low-frequency analog signal by use of digital pulses. Relatively imprecise digital pulses convey analog signal with relatively high precision. Amplifier implements sigma-delta modulation scheme. Circuit used wherever conventional amplifier needed. Includes medical instrumentation, switching-type power supplies, and other applications in which input voltages must be measured in presence of large common-mode voltages.
