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

6.00 AED

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. A CMOS transistor-pair, capable of swinging the output voltage to within 10mV of either supply-voltage terminal (at very high values of load impedance), is employed as the output circuit. The CA3130 Series circuits operate at supply voltages ranging from 5V to 16V, (±2.5V to ±8V). They can be phase compensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage.

Features:
  • Ideal for Single-Supply Applications
  • Common-Mode Input-Voltage Range Includes Negative Supply Rail; Input Terminals can be Swung 0.5V Below Negative Supply Rail
  • CMOS Output Stage Permits Signal Swing to Either (or both) Supply Rails
  • Pb-Free Plus Anneal Available (RoHS Compliant)

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
  • Voltage Followers (e.g. Follower for Single-Supply D/A Converter)
  • Voltage Regulators (Permits Control of Output Voltage Down to 0V)
  • Peak Detectors
  • Single-Supply Full-Wave Precision Rectifiers
  • Photo-Diode Sensor Amplifiers

The Arduino UNO Rev3 is based on the Atmega328 just like its predecessor, but it replaces the FTDI for the 16U2, this enables much faster upload speeds.
