description  
The TLE2682 offers the advantages of JFET-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 TLE2682 features two high-speed, 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’s 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, thus 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 TLE2682 operational  
amplifier section has output stages that can drive 20-mA loads to 2.3 V with a 5-V rail. With a 2-mA load, the  
output swing extends to 3.9 V.  
This amplifier design features a 25-V/µs minimum slew rate, which results in a high-power bandwidth. Settling  
time to 0.1% of a 10-V step (1-kΩ/100-pF load) is approximately 400 ns. Gain-bandwidth product is typically  
10 MHz with an 8-MHz minimum. The TLE2682 offers significant speed and noise advantages at a low 1.5-mA  
typical supply current per channel.  
The TLE2682 features a shutdown pin (FB/SD), which can be used to disable the switched-capacitor section.  
When disabled, the switched-capacitor voltage converter block draws less then 150 µA from the power supply,  
V .  
IN  
The switched-capacitor voltage converter block also provides an on-board regulator; with the addition of an  
external divider, a well-regulated output voltage is easily obtained. 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 V  
Additional filtering can be added to minimize switching noise.  
for use with the on-board regulator or external circuitry.  
REF  
The TLE2682 is characterized for operation over the industrial temperature range of −40°C to 85°C. This device  
is available in a 16-pin wide-body surface-mount package.
