Description
The CA3100 is a large signal wideband, high speed operational amplifier which has a unity gain cross over frequency (f T) of approximately 38MHz and an open loop, 3dB corner frequency of approximately 110kHz. It can operate at a total supply voltage of from 14V to 36V (±7V to ±18V when using split supplies) and can provide at least 18V P-P and 30mA P-P at the output when operating from ±15V supplies. The CA3100 can be compensated with a single external capacitor and has DC offset adjust terminals for those applications requiring offset null. (See Figure 1). The CA3100 circuit contains both bipolar and PMOS transis- tors on a single monolithic chip. Pinouts Part Number Information PART NUMBER (BRAND) TEMP. RANGE ( oC) PACKAGE PKG. NO.

Absolute Maximum Ratings Thermal Information Operating Conditions Temperature Range Thermal Resistance (Typical, Note 1)θJA (oC/W) θJC (oC/W) oC (SOIC - Lead Tips Only) CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. θJA is measured with the component mounted on an evaluation PC board in free air. 2. CA3100 does not contain circuitry to protect against short circuits in the output.
