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//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-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 VCC– – 0.3 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 to VCC+ – 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 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.

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 –55°C to 125°C.

设计工具

CIRCUIT060074 — 采用比较器的高侧电流检测电路

该高侧电流检测解决方案使用一个具有轨到轨输入共模范围的比较器,如果负载电流上升至超过 1A,则在比较器输出端 (COMP OUT) 产生过流警报 (OC-Alert) 信号。该实现中的 OC-Alert 信号低电平有效。因此,当超过 1A 阈值后,比较器输出变为低电平。实现了迟滞,使得当负载电流减小至 0.5 A(减少 50%)时,OC-Alert 将返回到逻辑高电平状态。该电路使用漏极开路输出比较器,从而对输出高逻辑电平进行电平转换,以控制数字逻辑输入引脚。对于需要驱动 MOSFET 开关栅极的应用,最好使用具有推挽输出的比较器。
