General Description

DW PACKAGE (TOP VIEW) 1OUT 1 1IN – 2 1IN + 3 VCC – 4 SCOUT 5 SCREF 6 OSC 7 SCIN 8 16 VCC + 15 2OUT 14 2IN – 13 2IN + 12 CAP – 11 GND 10 CAP + 9 FB/SD The TLE2662 offers the advantages of JFET-input operational amplifiers and rail-to-rail commonmode input voltage range with the convenience of single-supply operation.

By combining a switched-capacitor voltage converter with a dual operational amplifier in a single package, Texas Instruments now gives circuit designers new options for conditioning low-level signals in single-supply systems.

The TLE2662

Key Features

  • two low power, high-output drive JFET-input operational amplifiers with a switchedcapacitor building block. Using two external capacitors, the switched-capacitor network can be configured as a voltage inverter, generating a negative supply voltage capable of sourcing up to 100 mA. This supply functions not only as the amplifier negative rail but is also available to drive external circuitry. In this configuration, the amplifier common-mode input voltage range extends from the positive rail to be.
