The SSM2142 is an integrated differential-output buffer amplifier that converts a single-ended input signal to a balanced output signal pair with high output drive. By utilizing low noise thermally matched thin film resistors and high slew rate amplifiers, the SSM2142 helps maintain the sonic quality of audio systems by eliminating power line hum, RF interference, voltage drops, and other externally generated noise commonly encountered with long audio cable runs. Excellent rejection of common-mode noise and offset errors is achieved by laser trimming of the onboard resistors, assuring high gain accuracy. The carefully designed output stage of the SSM2142 is capable of driving difficult loads, yielding low distortion performance despite extremely long cables or loads as low as 600 Ohm, and is stable over a wide range of operating conditions.Based on a cross-coupled, electronically balanced topology, the SSM2142 mimics the performance of fully balanced transformer-based solutions for line driving. However, the SSM2142 maintains lower distortion and occupies much less board space than transformers while achieving comparable common-mode rejection performance with reduced parts count.The SSM2142 in tandem with the SSM2141 differential receiver establishes a complete, reliable solution for driving and receiving audio signals over long cables. The SSM2141 features an Input Common-Mode Rejection Ratio of 100 dB at 60 Hz. Specifications demonstrating the performance of this typical system are included in the data sheet.APPLICATIONS Audio Mix Consoles Distribution Amplifiers Graphic and Parametric Equalizers Dynamic Range Processors Digital Effects Processors Telecommunications Systems Industrial Instrumentation Hi-Fi Equipment

The AMP011 is a monolithic instrumentation amplifierdesigned for high-precision data acquisition and instrumentationapplications. The design combines the conventionalfeatures of an instrumentation amplifier with a high currentoutput stage. The output remains stable with high capacitanceloads (1 μF), a unique ability for an instrumentation amplifier.Consequently, the AMP01 can amplify low level signals fortransmission through long cables without requiring an outputbuffer. The output stage can be configured as a voltage orcurrent generator.Input offset voltage is very low (20 μV), which generallyeliminates the external null potentiometer. Temperature changeshave minimal effect on offset; TCVIOS is typically 0.15 μV/°C.Excellent low frequency noise performance is achieved with aminimal compromise on input protection. The bias current isvery low, less than 10 nA over the military temperature range.High common-mode rejection of 130 dB, 16-bit linearity at again of 1000, and 50 mA peak output current are achievablesimultaneously. This combination takes the instrumentationamplifier one step further towards the ideal amplifier.AC performance complements the superb dc specifications. TheAMP01 slews at 4.5 V/μs into capacitive loads of up to 15 nF, settlesin 50 μs to 0.01% at a gain of 1000, and boasts a healthy 26 MHzgain bandwidth product. These features make the AMP01 idealfor high speed data acquisition systems.The gain is set by the ratio of two external resistors over a range of0.1 to 10,000. A very low gain temperature coefficient of 10 ppm/°Cis achievable over the whole gain range. Output voltage swing isguaranteed with three load resistances: 50 Ω, 500 Ω, and 2 kΩ.Loaded with 500 Ω, the output delivers ±13.0 V minimum. Athermal shutdown circuit prevents destruction of the outputtransistors during overload conditions.The AMP01 can also be configured as a high performanceoperational amplifier. In many applications, the AMP01 can beused in place of op amp/power buffer combinations.1 Protected under U.S. Patents 4,471,321 and 4,503,381.

The AMP-02 is the first precision instrumentation amplifier available in an 8-pin package. Gain of the AMP-02 is set by a single external resistor, and can range from 1 to 10,000. No gain set resistor is required for unity gain.

Output offset voltage is below 4 mV and gain accuracy is better than 0.5% for gain of 1000. PMI's proprietary thin-film resistor process keeps the gain temperature coefficient under 50 ppm/°C.Due to the AMP-02's design, its bandwidth remains very high over a wide range of gain. Slew rate is over 4V/µS making the AMP-02 ideal for fast data acquisition systems.A reference pin is provided to allow the output to be referenced to an external DC level. This pin may be used for offset correction or level shifting as required. In the 8-pin package, sense is internally connected to the output.
