Frequently Asked Questions
What are the key specifications of OPA2137U?
The OPA2137U is a dual precision FET-input op-amp with 8 MHz gain-bandwidth product, 5 nV/√Hz input voltage noise, 5 fA input bias current, 10 V/μs slew rate, and ±5 V to ±15 V supply voltage. It operates from -40°C to +125°C in an 8-pin SOIC package.
What are typical applications for OPA2137U?
OPA2137U is commonly used in precision instrumentation amplifiers, medical and industrial sensor interfaces, data acquisition systems, active filters, and audio preamplifiers. Its ultra-low 5 fA input bias current makes it ideal for high-impedance transducers such as photodiodes and piezo sensors.
What compatible alternatives exist for OPA2137U?
Compatible alternatives include OPA2227 (lower noise, pin-compatible SOIC-8), OPA2134 (audio-grade, lower THD), and AD8066ARZ (Analog Devices, dual FET-input, higher speed). Always verify supply voltage and pin-out before substitution.
Is OPA2137U RoHS compliant and what package is available?
Yes, OPA2137U is RoHS compliant and lead-free. It is available in an 8-pin SOIC-8 package with 1.27 mm pitch. A DIP-8 variant (OPA2137P) is also offered by Texas Instruments for through-hole applications.
What is the minimum order quantity and price for OPA2137U?
OPA2137U has a minimum order quantity of 1 piece. Pricing starts at $3.08 per unit for single pieces and drops to $1.71 per unit at 10,000 pieces. Units are available from stock with global shipping.
