What are the key features of OPA4140AIDR-893485411?
- Quad FET-input op-amp with 11 MHz gain-bandwidth product and 20 V/µs slew rate for high-speed precision signal conditioning
- Wide supply range of 5 V to 36 V (±2.5 V to ±18 V) with rail-to-rail output for maximum dynamic range in industrial systems
- Low input bias current of 10 pA and low offset voltage enabling high-accuracy sensor interface and precision measurement circuits
What is OPA4140AIDR-893485411 used for?
The OPA4140AIDR is designed for precision signal conditioning in industrial data acquisition, active filter banks, and medical instrumentation where four matched op-amp channels in a single package reduce board area. Its wide 5 V to 36 V supply range and 10 pA input bias current make it ideal for high-impedance sensor interfaces such as photodiodes and piezoelectric transducers. Rail-to-rail output swing and 20 V/µs slew rate also suit audio and test-equipment front-end amplifier stages.

Frequently Asked Questions
What gain-bandwidth product and slew rate does the OPA4140AIDR provide for active filter designs?
The OPA4140AIDR offers an 11 MHz gain-bandwidth product and a 20 V/µs slew rate, enabling accurate Sallen-Key or multiple-feedback filter topologies up to several hundred kilohertz. These specifications, combined with a 10 pA FET input bias current, keep errors low when driving filters from high-impedance sources in precision measurement systems.
Over what supply voltage range can OPA4140AIDR operate, and how does this affect its use in industrial sensor circuits?
OPA4140AIDR operates from a single 5 V to 36 V supply or a split ±2.5 V to ±18 V supply, giving designers flexibility for both 5 V microcontroller systems and higher-voltage industrial 24 V rails. The rail-to-rail output ensures the full dynamic range is usable, which is critical when digitizing small sensor signals with a 12-bit or 16-bit ADC.
When is OPA4140AIDR a better choice than OPA4134 for photodiode transimpedance amplifier arrays?
When the photodiode leakage current is below 100 pA, OPA4140's 10 pA FET input bias current produces less than 1% current-measurement error compared to OPA4134's bipolar input, which can draw nA-level bias currents. The quad channel count also lets a single OPA4140AIDR replace four discrete amplifiers, cutting component count by 75% in four-channel detector arrays.
What package and pin count does the OPA4140AIDR use, and what board footprint should be planned?
OPA4140AIDR is housed in a 14-pin SOIC package with a body size of 8.65 mm x 3.91 mm and 1.27 mm pin pitch, which is compatible with standard SMT reflow processes. The SOIC-14 footprint is widely supported by EDA tools and allows manual rework, making it suitable for prototyping as well as volume production on 0.1 mm tolerance PCBs.
