description (continued)

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 TLE2141M and TLE2141AM are useful for low-droop sample and holds

and direct buffering of long cables, including four 20-mA current loops.

The special design also exhibits an improved insensitivity to inherent IC component mismatches as is evidenced

by a 500-

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

may flow out of each input exceeding the lower common-mode input range. The all NPN output stage provides

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.

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 overdriven beyond the limits of

recommended output swing.

Both the TLE2141M and TLE2141AM 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 M-suffix

is characterized for operation over the full military temperature range of – 55

°C to 125°C.
