OPA137 series FET- input operational amplifiers are designed for low cost and miniature applications. In addition to small size (SOT-23-5 and MSOP-8 packages), amplifiers provide low input bias current (±10pA), low quiescent current (120µA/ channel), and high open-loop gain (145dB).

Either single (+4.5V to +36V) or dual (±2.25V to ±18V) supplies can be used. The input common-mode voltage range includes the positive supply an excellent choice for many single-supply applications. Single, dual, and quad versions have identical specifications for maximum design flexibility.

OPA137 op amps are easy to use and free from phase inversion and overload problems found in some FET- input amplifiers. High performance, including linearity, is maintained as the amplifiers swing to the specified limits. In addition, the combination of high slew rate (4.5V/µs) and wide bandwidth (1.1MHz) provide fast settling time verifies good dynamic response. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

The single (OPA137) packages are the tiny 5-lead SOT-23-5 surface mount, SO-8 surface mount, and 8-pin DIP. The dual (OPA2137) comes in the miniature MSOP-8 surface mount, and the SO-8 surface mount. The quad (OPA4137) packages are the SO-14 surface mount and the 14-pin DIP. All are specified from – 40°C to +85°C and operate from – 55°C to +125°C. A SPICE macro-model is available for design analysis.

CIRCUIT060013 — 采用 T 网络反馈电路的反相放大器

该设计将输入信号 VIN 反相并应用 1000V/V 或 60dB 的信号增益。具有 T 反馈网络的反相放大器可用于获得高增益,而无需 R4 具有很小的值或反馈电阻器具有很大的值。

该电路结合了一个反相和同相放大器,可使基准电压在正负输入电压范围内进行调节。可通过增加增益来提高最大负基准电压电平。
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。实施磁滞以确保在负载电流减小至 0.5A(减少 50%)时,OC-Alert 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。
