Frequently Asked Questions
How low is the input bias current of the OPA2320AIDR?
The OPA2320AIDR has a maximum input bias current of just 0.9 pA at 25°C, making it well suited for high-impedance photodiode and sensor interface circuits where leakage errors must stay minimal.
Why is the OPA2320AIDR's common-mode rejection ratio significant for precision designs?
With a minimum CMRR of 100 dB and typical 114 dB, the OPA2320AIDR suppresses common-mode noise effectively, improving accuracy in differential sensor measurement and instrumentation amplifier front-end stages.
How is the OPA2320AIDR housed for board-level assembly?
The OPA2320AIDR is packaged in a compact 8-pin small-outline (SOIC) package, providing two independent amplifier channels in a single low-profile footprint suited for boards with limited component height clearance.
In what type of signal-chain designs does the OPA2320AIDR's zero-crossover architecture provide an advantage?
Its zero-crossover topology paired with 20 MHz bandwidth and rail-to-rail input/output swing lets the OPA2320AIDR maintain low distortion near the supply rails, benefiting multiplexed data-acquisition front ends and dual-channel active filter designs requiring wide dynamic range.
