description (continued)
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/
μ
s 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-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 TLE2141 and TLE2141A 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-
μ
V maximum offset voltage and 1.7-
μ
V/
°
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 TLE2141 and TLE2141A 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 –55
°
C to 125
°
C.
