Operational Amplifiers
Precision instrumentation amplifiers and differential ADC drivers, pin- and spec-compatible with international parts.
AD620 equivalentYS620
A gain-programmable, high-performance instrumentation amplifier with high CMRR over a wide frequency range — above 80 dB up to 10 kHz at G = 1. Gain is set from 1 to 1000 with a single resistor; low offset, low drift and high gain accuracy suit bridge-type signal conditioning.
- Supply
- ±2.3 V to ±18 V
- Input offset
- 40 µV max.
- Offset drift
- 0.3 µV/°C max.
- Noise
- 7 nV/√Hz max.
OP400 equivalentYS400
A high-performance, low-power precision quad op-amp, function-compatible with the OP400. ±15 V operation (±20 V absolute maximum), on-chip trimmed offset with no external nulling, under 725 µA per amplifier, −55 to +125 °C.
- Input offset
- ≤150 µV
- Offset drift
- ≤1.2 µV/°C
- Supply current
- ≤725 µA/channel
- Open-loop gain
- ≥3000 V/mV
AD8032 equivalentYS8032
A dual, single-supply voltage-feedback amplifier with rail-to-rail input and output: +2.7 V, +5 V or ±5 V supply, under 1100 µA per channel, 65 MHz small-signal bandwidth and 22 V/µs slew rate — suited to single-supply ADC buffering.
- Supply current
- 1100 µA/channel
- Supply
- +2.7 V, +5 V, ±5 V
- −3 dB bandwidth
- 65 MHz (G = +1)
- Slew rate

AD8042 equivalentYS8042
A dual, high-bandwidth rail-to-rail amplifier for driving A/D converters: 6.0 mA per amplifier from +3 V, +5 V or ±5 V, 120 MHz small-signal bandwidth and 130 V/µs slew rate.
- Supply current
- 6.0 mA/amp
- Supply
- +3 V, +5 V, ±5 V
- −3 dB bandwidth
- 120 MHz (G = +1)
- Slew rate
- 130 V/µs
AD8138 equivalentYS8138
A differential ADC driver built on a domestic high-voltage complementary bipolar process, usable single-ended-to-differential or differential-to-differential: 300 MHz −3 dB bandwidth, very low harmonic distortion, VOCM-adjustable output common mode, for driving 10- to 16-bit ADCs.
- −3 dB bandwidth
- 300 MHz (G = +1)
- Slew rate
- ≥880 V/µs
- Supply
- +5 V / ±5 V
- Operating temp.
- −55 to +125 °C
AD8139 equivalentYS8139
A single-ended-to-differential or differential-to-differential rail-to-rail amplifier on a domestic high-voltage complementary bipolar process: 220 MHz −3 dB bandwidth, high SFDR, very low distortion and noise — an ideal driver for high-precision ADCs.
- −3 dB bandwidth
- 220 MHz (G = +1)
- Input noise
- 2.25 nV/√Hz
- Slew rate
- 600 V/µs
