TheTLE2662offerstheadvantagesofJFET-input  
operational amplifiers and rail-to-rail common-  
mode 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 features two low power, high-output drive JFET-input operational amplifiers with a switched-  
capacitor 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 below ground, providing true  
rail-to-rail inputs from a single supply. Furthermore, the outputs can swing to and below ground while sinking  
over 25 mA. This feature was previously unavailable in operational amplifier circuits. The TLE2662 operational  
amplifier section has output stages that can drive 100-Ω loads to 2.5 V from a 5-V rail. With a 10-kΩ load, the  
output swing extends to 3.5 V and can include the positive rail with a pullup resistor.  
This operational amplifier offers the high slew rate, wide bandwidth, and high input impedance commonly  
associated with JFET-input amplifiers, making the TLE2662 operational amplifier section suited for amplifying  
fast signals without loading the signal source. When not sourcing or sinking current into a load, the amplifier  
consumes only microamperes of supply current, thereby reducing the drain on and extending the life of the  
power supply.  
The TLE2662 features a shutdown pin (FB/SD), which can be used to disable the switched capacitor section.  
When disabled, the voltage converter block draws less than 150 µA from the power supply. This feature,  
combined with the operational amplifier’s low quiescent current, makes the TLE2662 a real power saver in the  
standby mode.  
The switched-capacitor building block also provides an on-board regulator; with the addition of an external  
divider, awell-regulatedoutputvoltageiseasilyobtained. Additionalfilteringcanbeaddedtominimizeswitching  
noise. The internal oscillator runs at a nominal frequency of 25 kHz. This can be synchronized to an external  
clock signal or can be varied using an external capacitor. A 2.5-V reference is brought out to SCREF for use  
with the on-board regulator or external circuitry.
