Frequently Asked Questions
What is the gain-bandwidth product and slew rate of the OPA341NA/250?
The OPA341NA/250 has a gain-bandwidth product (GBW) of 5.5MHz and a slew rate of 6V/us. This combination provides fast settling and accurate signal reproduction for audio, sensor, and moderate-speed data acquisition applications operating from a single supply.
What is the input bias current of the OPA341NA/250?
The OPA341NA/250 features an exceptionally low typical input bias current of 10pA (0.00001µA) at 25°C with a maximum of 2nA average. This makes it ideal for high-impedance sources such as photodiodes, pH electrodes, and piezoelectric sensors where bias current causes significant measurement error.
Does the OPA341NA/250 support rail-to-rail operation?
Yes, the OPA341NA/250 supports rail-to-rail input common-mode range and rail-to-rail output swing. This allows the amplifier to process signals that span the entire supply range, maximizing dynamic range and simplifying circuit design in single-supply systems running from 3.3V or 5V.
What is the CMRR of the OPA341NA/250?
The OPA341NA/250 achieves a typical common-mode rejection ratio (CMRR) of 90dB and a minimum of 76dB. This high CMRR ensures the amplifier rejects noise and interference common to both inputs, which is essential in sensor interfaces subject to ground noise and electromagnetic interference.
What package does the OPA341NA/250 come in?
The OPA341NA/250 is packaged in a SOT-23-6 (6-pin SOT-23) surface-mount package. This small footprint supports high-density PCB layouts in portable instruments, wearables, and compact industrial sensors, while remaining compatible with standard automated assembly and reflow soldering processes.
