Frequently Asked Questions
What is the input bias current of the OPA1654AIDR?
The OPA1654AIDR features an extremely low maximum input bias current (IIB) of 0.0001µA (100pA) at 25°C, making it ideal for high-impedance source applications such as photodiode amplifiers and precision sensor interfaces where leakage current must be minimized.
What are the typical applications for the OPA1654AIDR?
The OPA1654AIDR is commonly used in professional audio preamplifiers, active filters, precision instrumentation amplifiers, data acquisition systems, and sensor signal conditioning circuits. Its low noise and high CMRR of 110dB make it especially suitable for audio and measurement applications requiring low distortion.
What package does the OPA1654AIDR come in, and is it RoHS compliant?
The OPA1654AIDR is available in a 14-pin SOIC (Small Outline Integrated Circuit) package, which is compact and suitable for surface-mount assembly. It is fully RoHS compliant (Pb-free), as indicated by its Pbfree Code of Yes, supporting environmentally conscious manufacturing.
Can the OPA1654AIDR replace other quad op-amps in existing designs?
The OPA1654AIDR is pin-compatible with standard quad op-amp footprints in 14-pin SOIC packages. It can typically replace devices like the TL074 or NE5534 quad variants in audio and precision signal-chain applications, offering significantly lower noise and bias current, though supply voltage and power requirements should be verified before substitution.
