DESCRIPTION/ORDERING INFORMATION
The TLE2142 device is a high-performance, internally compensated operational amplifier built using the Texas
Instruments complementary bipolar Excalibur? process. It is a pin-compatible upgrade to standard industry
products.
The design incorporates an input stage that simultaneously achieves low audio-band noise of 10.5 nV/√Hz with a
10-Hz 1/f corner and symmetrical 40-V/ms slew rate typically with loads up to 800 pF. The resulting low distortion
and high power bandwidth are important in high-fidelity audio applications. A fast settling time of 340 ns to 0.1%
of a 10-V step with a 2-kΩ/100-pF load is useful in fast actuator/positioning drivers. Under similar test conditions,
settling time to 0.01% is 400 ns.
The device is stable with capacitive loads up to 10 nF, although the 6-MHz bandwidth decreases to 1.8 MHz at
this high loading level. As such, the TLE2142 is useful for low-droop sample-and-holds and direct buffering of
long cables, including 4-mA to 20-mA current loops.
The special design also exhibits an improved insensitivity to inherent integrated circuit component mismatches as
is evidenced by a 500-mV maximum offset voltage and 1.7-mV/°C typical drift. Minimum common-mode rejection
ratio and supply-voltage rejection ratio are 85 dB and 90 dB, respectively.
Device performance is relatively independent of supply voltage over the ±2-V to ±22-V range. Inputs can operate
between VCC– – 0.3 V to VCC+ – 1.8 V without inducing phase reversal, although excessive input current may flow
out of each input exceeding the lower common-mode input range. The all-npn output stage provides a nearly
rail-to-rail output swing of VCC– + 0.1 V to VCC+ – 1 V under light current-loading conditions. The device can
sustain shorts to either supply, because output current is internally limited, but care must be taken to ensure that
maximum package power dissipation is not exceeded.
The TLE2142 can also be used as a comparator. Differential inputs of VCC± can be maintained without damage
to the device. Open-loop propagation delay with TTL supply levels is typically 200 ns. This gives a good
indication as to output stage saturation recovery when the device is driven beyond the limits of recommended
output swing.
The TLE2142 device is available in industry-standard 8-pin small-outline (D) packages. The device is
characterized for operation from –40°C to 125°C.
