OP400GSZ vs OP471GS vs OP400GSZ-REEL Comparison

GENERAL DESCRIPTION The OP400 is the first monolithic quad operational amplifier that features OP77-type performance. Precision performance is not sacrificed with the OP400 to obtain the space and cost savings offered by quad amplifiers. FEATURES Low input offset voltage: 150 μV maximum Low offset voltage drift over –55°C to +125°C: 1.2 pV/°C maximum Low supply current (per amplifier): 725 μA maximum High open-loop gain: 5000 V/mV minimum Input bias current: 3 nA maximum Low noise voltage density: 11 nV/√Hz at 1 kHz Stable with large capacitive loads: 10 nF typical Pin-compatible to LM148, HA4741, RM4156, and LT1014, with improved performance Available in die form

Product Details The OP471 is a monolithic quad op amp featuring low-noise, 11nV/(root)Hz Max at 1kHz, excellent speed, 8V/µs typical, a gain-bandwidth of 6.5MHz, and unity-gain stability. The OP471 has an input offset voltage under 0.8mV and an input offset voltage drift below 4µV/°C. guaranteed over the full military temperature range. Open loop gain of the OP471 is over 500,000 into a 10k Ohm load insuring outstanding gain accuracy and linearity. The input bias current is under 25nA limiting errors due to signal source resistance. The OP471"s CMR of over 105dB and PSRR of under 5.6µV/V significantly reduce errors caused by ground noise and power supply fluctuations. The OP471 offers excellent amplifier matching which is important for applications such as multiple gain blocks, low-noise instrumentation amplifiers, quad buffers and low-noise active filters. The OP471 conforms to the industry standard 14-pin DIP pinout. It is pin compatible with the OP-11, LM 148/149, HA4741, RM4156, MC33074, TL084 and TL074 quad op amps and can be used to upgrade systems using these devices. For applications requiring even lower voltage noise the OP470, with a voltage density of 5nV/(root)Hz Max at 1kHz, is recommended. ### Features and Benefits
