Low Power CMOS Quad Operational Amplifier

Low Power CMOS Quad Operational Amplifier - LPC660
 

Description

The LPC660 CMOS Quad operational amplifier is ideal for operation from a single supply. It features a wide range of operating voltages from +5V to +15V and features rail-to-rail output swing in addition to an input common-mode range that includes ground. Performance limitations that have plagued CMOS amplifiers in the past are not a problem with this design. Input VOS, drift, and broadband noise as well as voltage gain (into 100 kΩ and 5 kΩ) are all equal to or better than widely accepted bipolar equivalents, while the power supply requirement is typically less than 1 mW.

This chip is built with National's advanced Double-Poly Silicon-Gate CMOS process.

See the LPC662 datasheet for a Dual CMOS operational amplifier and LPC661 datasheet for a single CMOS operational amplifier with these same features.

Features

  • Rail-to-rail output swing
  • Micropower operation: (1 mW)
  • Specified for 100 kΩ and 5 kΩ loads
  • High voltage gain: 120 dB

  • Low offset voltage drift: 1.3 μV/°C
  • Ultra low input bias current: 2 fA
  • Input common-mode includes V
  • Operation range from +5V to +15V
  • Low distortion: 0.01% at 1 kHz
  • Slew rate: 0.11 V/μs
  • Full military temp. range available
