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 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 900-µV maximum offset voltage and 1.7-µV/°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 V 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 V 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.
The TLE214x devices are available in industry-standard 8-pin and 16-pin small-outline packages. The devices
are characterized for operation from –55°C to 125°C.
