The OP-97 is a low-power alternative to the industry-standard OP-07 precision amplifier. The OP-97 maintains the standards of performance set by the OP-07 while utilizing only 600µA supply current, less than 1/6 that of an OP-07. Offset voltage is an ultra-low 25µV, and drift over temperature is below 0.6µV/°C. External offset trimming is not required in the majority of circuits.Improvements have been made over OP-07 specifications in several areas. Notable is bias current, which remains below 250pA over the full military temperature range. The OP-97 is ideal for use in precision long-term integrators or sample-and-hold circuits that must operate at elevated temperatures.Common-mode rejection and power-supply rejection are also improved with the OP-97, at 114dB minimum over wider ranges of common-mode or supply voltage. Outstanding PSR, a supply range specified from ±2.25V to ±20V and the OP-97's minimal power requirements combine to make the OP-97 a preferred device for portable and battery-powered instruments.The OP-97 conforms to the OP-07 pinout, with the null potentimeter connected between pins 1 and 8 with the wiper to V+. The OP-97 will upgrade circuit designs using 725, OP05, OP07, OP12, and 1012 type amplifiers. It may replace 741-type amplifiers in circuits without nullling or where the nulling circuitry has been removed.

The REF-01/REF-02 are precision 10V and 5V bandgap references which provide stable output voltages over a wide range of operating conditions. Output voltage is accurate to ±0.3% with a low 5ppm/°C typical temperature coefficient. The REF-01 and REF-02 are excellent choices for applications where low drift, moderate accuracy, low power consumption and low cost are considerations.The REF-02 includes a temperature output pin which provides a linear voltage proportional to absolute temperature.For lower drift and higher accuracy references, please see the LT1019 and LT1021 data sheets.ApplicationsA/D and D/A ConvertersPrecision RegulatorsConstant Current SourcesV/F ConvertersBridge Excitation

TheREF01/ REF02 /REF03series of precision voltage references provide a stable 10.0 V, 5.0 V, or 2.5 V output with minimal change in response to variations in supply voltage, ambient temperature or load conditions. The devices are available in 8-lead SOIC, PDIP, CERDIP, and TO-99 packages, as well as 20-terminal LCC packages (883 only), furthering the usability of the devices in both standard and high stress applications.With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is also provided on the device for fine adjustment of the output voltage.The small footprint, wide supply range, and application versatility make the REF0x series of references ideal for general-purpose and space-constrained applications.Newer designs should use theADR01/ADR02/ADR03/ADR06series of references, which offer higher accuracy and temperature stability over a wider operating temperature range, while maintaining full pin-for-pin compatibility with the REF01 / REF02 / REF03 series.
