Frequently Asked Questions
What is the quiescent current of LPV521?
The LPV521 draws only 400nA typical quiescent current, making it one of the lowest power op-amps available. A CR2032 coin cell (230mAh) could power this op-amp for over 65 years from IQ alone, ideal for always-on sensing applications.
What supply voltage does LPV521 require?
The LPV521 operates from 1.6V to 5.5V single supply, covering coin cell (3V), Li-ion (3.7V), and standard 5V rails. Rail-to-rail input and output maximizes usable signal range even at the lowest supply voltage.
What is the bandwidth limitation of LPV521?
The LPV521 has 6.2kHz gain-bandwidth product and 2.4mV/ms slew rate, reflecting its ultra-low power design. It is suitable for DC to low-frequency signals (sub-kHz). For higher speed with low power, consider TI's LPV811 (8µA, 450kHz GBW).
Can LPV521 drive a load directly?
The LPV521 can drive loads up to 600Ω to rail-to-rail output. For lower impedance loads, an external buffer may be needed. Output short-circuit protection is included. The low output current capability is consistent with its nanopower design philosophy.
