  • Noise Performance: 1/f noise ~250 nV pp (0.1–10 Hz); input-referred noise density ~5.1 nV/√Hz
  • Slew Rate: ~20 V/µs, supports dynamic signal bandwidths
  • Supply Current: Efficient operation at ~2 mA typical
  • Operating Temp Range: –40 °C to +125 °C, robust for industrial environments
  • Package / Material: RoHS-compliant, compact VSSOP (DGK) 8-pin SMD

Usage Information and Benefits

This versatile op amp stands out with its high precision and low noise, making it ideal for applications such as sensor signal conditioning, precision data acquisition (DAQ), analytical instrument front-ends, and test-and-measurement systems. The rail-to-rail output maximises dynamic range in low-voltage systems, while the ultra-low bias current supports accurate interfacing with capacitive sensors or high-impedance sources. Moreover, its wide supply voltage tolerance and compact VSSOP footprint make it perfect for space-constrained, industrial-grade PCBs.

Why Choose this Over Generic Op-Amps?

Backed by the reliability of Texas Instruments, this op-amp offers superior precision, thermal performance, and noise control compared to generic alternatives. It features no phase reversal, ensuring signal integrity, and is engineered for consistent performance across harsh industrial conditions.
