Microchip Technology, Inc. 400 kHz, Single Zero-Drift Op Amp TC7652

TC7652 is a lower noise version of the TC7650, sacrificing some input specifications (bias current and bandwidth) to achieve a 10x reduction in noise. All the other benefits of the chopper technique are present, i.e., freedom from offset adjust, drift and reliability problems from external trim components. Like the TC7650, the TC7652 requires only two non-critical external caps for storing the chopped null potentials. There are no significant chopping spikes, internal effects or overrange lockup problems. Additional Features Drift Operation Voltage: 5 to 16 Single and Split Supply Low Noise
