The SSM2135 dual audio operational amplifier permits excel-lent performance in portable or low power audio systems, with an operating supply range of 4 V to 36 V or ±2 V to ±18 V. The unity-gain stable device has very low voltage noise of 5.2 nV/√Hz, and total harmonic distortion plus noise below 0.01% over normal signal levels and loads. Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage1 permits output swing approaching the rail under moderate load conditions. Under severe loading, the SSM2135 still maintains a wide output swing with ultralow distortion. Particularly well suited for computer audio systems and portable digital audio units, the SSM2135 can perform preamplification, headphone and speaker driving, and balanced line driving and receiving. Additionally, the device is ideal for input signal conditioning in single-supply, Σ-Δ, analog-to-digital converter subsystems such as the AD1877. The SSM2135 makes an ideal single-supply stereo output amplifier for audio digital-to-analog converters (DACs) because of its low noise and distortion.The SSM2135 is available in an 8-lead plastic SOIC package and is guaranteed for operation over the extended industrial temperature range of −40°C to +85°C.

The OPx177 family consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and drift, low input bias current, low noise, and low power consump-tion. Outputs are stable with capacitive loads of over 1000 pF with no external compensation. Supply current is less than 500 μA per amplifier at 30 V. Internal 500 Ω series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal.Unlike previous high voltage amplifiers with very low offset voltages, the OP1177 (single) and OP2177 (dual) amplifiers are available in tiny 8-lead surface-mount MSOP and 8-lead narrow SOIC packages. The OP4177 (quad) is available in TSSOP and 14-lead narrow SOIC packages. Moreover, specified performance in the MSOP and the TSSOP is identical to performance in the SOIC package. MSOP and TSSOP are available in tape and reel only.The OPx177 family offers the widest specified temperature range of any high precision amplifier in surface-mount packaging. All versions are fully specified for operation from −40°C to +125°C for the most demanding operating environments.Applications for these amplifiers include precision diode power measurement, voltage and current level setting, and level detection in optical and wireless transmission systems. Additional applications include line-powered and portable instrumentation and controls—thermocouple, RTD, strain-bridge, and other sensor signal conditioning—and precision filters.Applications Wireless base station control circuits Optical network control circuits Instrumentation Sensors and controls Thermocouples Resistor thermal detectors (RTDs) Strain bridges Shunt current measurements Precision filters

The OP270 is a high performance, monolithic, dual operational amplifier with exceptionally low voltage noise density (5 nV/√Hz maximum at 1 kHz). It offers comparable performance to the industry-standard OP27 from Analog Devices, Inc. The OP270 features an input offset voltage of less than 75 μV and an offset drift of less than 1 μV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is more than 1,500,000 into a 10 kΩ load, ensuring excellent gain accuracy and linearity, even in high gain applications. The input bias current is less than 20 nA, which reduces errors due to signalsource resistance. With a common-mode rejection (CMR) of greater than 106 dB and a power supply rejection ratio (PSRR) of less than 3.2 μV/V, the OP270 significantly reduces errors due to ground noise and power supply fluctuations. The power consumption of the dual OP270 is one-third less than two OP27 devices, a significant advantage for power conscious applications. The OP270 is unity-gain stable with a gain bandwidth product of 5 MHz and a slew rate of 2.4 V/μs.The OP270 offers excellent amplifier matching, which is important for applications such as multiple gain blocks, low noise instrumentation amplifiers, dual buffers, and low noise active filters.The OP270 conforms to the industry-standard 8-lead CERDIP and PDIP pinouts. For higher speed applications, the ADA4004-2 or the AD8676 are recommended. For a quad op amp, see the OP470 data sheet.
