The TLC3702 consists of two independent micropower voltage comparators designed to operate from a single supply and be compatible with modern HCMOS logic systems. They are functionally similar to the LM339 but use one-twentieth of the power for similar response times. The push-pull CMOS output stage drives capacitive loads directly without a power-consuming pullup resistor to achieve the stated response time. Eliminating the pullup resistor not only reduces power dissipation, but also saves board space and component cost. The output stage is also fully compatible with TTL requirements.

Texas Instruments LinCMOS™ process offers superior analog performance to standard CMOS processes. Along with the standard CMOS advantages of low power without sacrificing speed, high input impedance, and low bias currents, the LinCMOS™ process offers extremely stable input offset voltages with large differential input voltages. This characteristic makes it possible to build reliable CMOS comparators.

The TLC3702C is characterized for operation over the commercial temperature range of 0°C to 70°C. The TLC3702I is characterized for operation over the extended industrial temperature range of –40°C to 85°C. The TLC3702M is characterized for operation over the full military temperature range of –55°C to 125°C.

AMP-PDK-EVM — 放大器高性能开发套件评估模块

放大器高性能开发套件 (PDK) 是一款用于测试常见运算放大器参数的评估模块 (EVM) 套件，与大多数运算放大器和比较器均兼容。该 EVM 套件提供了一个主板，主板上具有多个插槽式子卡选项以满足封装需求，使工程师能够快速评估和验证器件性能。

AMP-PDK-EVM 套件支持五种常用的业界通用封装，包括：

  • D（SOIC-8 和 SOIC-14）
  • PW (TSSOP-14)
  • DGK (VSSOP-8)
  • DBV（SOT23-5 和 SOT23-6）
  • DCK（SC70-5 和 SC70-6）

CIRCUIT060079 — 采用比较器的过压保护电路

这个过压保护电路使用具有推挽输出级的高压比较器来控制将电源连接到负载的 P 沟道 MOSFET。当电源电压超过过压阈值 (VOVER) 时，比较器的输出变为高电平，并通过打开 P 沟道 MOSFET 将负载与电源断开。同样，当电源电压低于 VOVER 时，比较器的输出为低电平并将负载连接到电源。
