Product Folder Sample & Buy Support & Community Tools & Software Technical Documents OPA132, OPA2132, OPA4132 SBOS054B – JANUARY 1995 – REVISED SEPTEMBER 2015 OPAx132 High-Speed FET-Input Operational Amplifiers 1 Features 3 Description • • • • • • • • • The OPAx132 series of FET-input operational amplifiers provides highspeed and excellent DC performance. The combination of high slew rate and wide bandwidth provide fast settling time. Single, dual, and quad versions have identical specifications for maximum design flexibility. High performance grades are available in the single and dual versions. All are ideal for general-purpose, audio, data acquisition and communications applications, especially where high source impedance is encountered. 1 FET input: IB = 50 pA Maximum Wide Bandwidth: 8 MHz High Slew Rate: 20 V/µs Low Noise: 8nV/√Hz (1 kHz) Low Distortion: 0.00008%) High Open-loop Gain: 130 dB (600-Ω load) Wide Supply Range: ±2.5 to ±18V Low Offset Voltage: 500 µV Maximum Single, Dual, and Quad Versions The OPAx132 operational amplifiers are easy to use and free from phase inversion and overload problems often found in common FET-input operational amplifiers. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range. The OPAx132 series of operational amplifiers are stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. Dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. 2 Applications • • • • • • SAR ADC Driver Voltage Reference Buffer Trans-impedance Amplifier Photodiode Amplifier Active Filters Integrators Low Noise JFET Input Current Noise (fA/√Hz) Voltage Noise (nV/√Hz) 1k Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages.

バー・ブラウンは、アメリカはアリゾナ州に本拠があるアナログ系ICの名門ブランドであった。その設立は1956年という老舗。このブランド名は、高級なオーディオ/AV機器のDAC（D/Aコンバーター）やオペアンプ（アナログ増幅素子）にお決まりのように見受けられた。とりわけPCM1704は、高級オーディオ用のマルチビットDACを唯一生産しつづけているBB＝バー・ブラウンの象徴的な存在だ。
