The TLE214x and TLE214xA devices are high-performance, internally compensated operational
amplifiers built using Texas Instruments complementary bipolar Excalibur process. The
TLE214xA is a tighter offset voltage grade of the TLE214x. Both are pin-compatible upgrades
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/us 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 340ns to 0.1% of a 10-V step with a 2-k
/100-pF load is useful in fast actuator/positioning drivers. Under similar test conditions,
settling time to 0.01% is 400 ns.
The devices are 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 TLE214x and TLE214xA are 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-uV maximum offset voltage and 1.7-uV/°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 V
CC-
- 0.3 to V
CC+
- 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 V
CC-
- 0.1 to V
CC+
- 1 V under light current-loading conditions. The device can sustain shorts to
either supply since output current is internally limited, but care must be taken to ensure that
maximum package power dissipation is not exceeded.
Both versions can also be used as comparators. Differential inputs of V
CC±
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.
Both the TLE214x and TLE214xA are available in a wide variety of packages, including both
the industry-standard 8-pin small-outline version and chip form for high-density system
applications. The C-suffix devices are characterized for operation from 0°C to 70°C, I-suffix
devices from -40°C to 105°C, and M-suffix devices over the full military temperature range of
