CA3130E Datasheet

15MHz, BiMOS Operational Amplifier with MOSFET Input/CMOS Output FN817.4


CA3130A and CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors. Gate-protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current, and exceptional speed performance. The use of PMOS transistors in the input stage results in common-mode input-voltage capability down to
0.5V below the negative-supply terminal, an important attribute in single-supply applications.

• Ground-Referenced Single Supply Amplifiers
• Fast Sample-Hold Amplifiers
• Long-Duration Timers/Monostables
• High-Input-Impedance Comparators(Ideal Interface with Digital CMOS)
• High-Input-Impedance Wideband Amplifiers
