Frequently Asked Questions
What supply voltage range and input bias current specs make the MCP619-I/ST suitable for battery-powered sensor circuits?
The MCP619-I/ST operates from a 2.3 V to 5.5 V single supply, covering single-cell Li-ion and two-cell alkaline systems. Its maximum input bias current of 5 nA at 25 °C keeps leakage-induced offset negligible even with high-impedance sensors, making it an excellent fit for low-power, portable measurement applications.
How does the CMRR specification of the MCP619-I/ST affect noise rejection in differential sensing applications?
With a typical common-mode rejection ratio of 100 dB and a guaranteed minimum of 80 dB, the MCP619-I/ST suppresses common-mode interference effectively. In a 5 V bridge-sensor circuit, 100 dB CMRR means a 1 V common-mode disturbance contributes only 10 µV of differential error, preserving measurement accuracy across 4 independent amplifier channels.
What board-space advantage does the 14-pin TSSOP package of the MCP619-I/ST offer compared with four separate single op-amp packages?
The TSSOP-14 package integrates all 4 amplifiers into a footprint of roughly 5 mm × 4.4 mm, replacing four individual SOT-23-5 or SC-70-5 packages that would collectively occupy more than twice the PCB area. This density benefit is especially valuable in compact industrial transmitter or wearable medical modules where board space is at a premium.
