JFET input stage, single-supply range
The TL031ID is a single JFET-input operational amplifier from Texas Instruments, in an 8-SOIC package. It delivers a 1.1 MHz gain-bandwidth product and a 5.1 V/µs slew rate, with a supply span from 10 V to 30 V. The JFET input stage keeps input bias current at 2 pA typical, which matters for high-impedance sensor front-ends where bias current error would otherwise dominate the offset budget.
Supply current and temperature range
Quiescent supply current is 217 µA, making it suitable for battery-powered or power-sensitive analog signal chains where every microamp counts. Rated for -40°C to 85°C operation, the TL031ID covers industrial temperature environments — control cabinets, outdoor telecom, and factory-floor sensor conditioning.
Lifecycle and sourcing
Texas Instruments lists the TL031ID as Active and ROHS3 compliant. No end-of-life notice or successor is recorded — it remains a current-production part for new and existing designs.
