•
• The 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 noncritical external caps
for storing the chopped null potentials. There are no
significant chopping spikes, internal effects or overrange lockup problems. Low Offset Over Temperature Range: 10V
Ultra Low Long Term Drift: 150nV/Month
Low Temperature Drift: 100nV/C
Low DC Input Bias Current: 15pA
High Gain, CMRR and PSRR: 110dB Min
Low Input Noise Voltage: 0.2Vp-p (DC to 1Hz)
Internally Compensated for Unity Gain Operation …
