MAX988 - High-Speed / Micropower / Low-Voltage / SOT23 / Rail-to-Rail I/O Comparators

Description

The MAX987/MAX988/MAX991/MAX992/MAX995/ MAX996 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs.

Their operating voltage ranges from +2.5V to +5.5V, making them ideal for both 3V and 5V systems.

Features

  • 120ns Propagation Delay.
  • 48µA Quiescent Supply Current.
  • +2.5V to +5.5V Single-Supply Operation.
  • Common-Mode Input Voltage Range Extends 250mV Beyond the Rails.
  • Push-Pull Output Stage Sinks and Sources 8mA Current (MAX987/MAX991/MAX995).
  • Open-Drain Output Voltage Extends Beyond VCC (MAX988/MAX992/MAX996).
  • Unique Output Stage Reduces Output Switching Current, Minimizing Overall Power Consumption.
  • 100µA Supply Current at 1MHz.

19-1266; Rev 2; 1/07 MAX987/MAX988/MAX991/MAX992/MAX995/MAX996 High-Speed, Micropower, Low-Voltage, SOT23, Rail-to-Rail I/O Comparators ________________General Description The MAX987/MAX988/MAX991/MAX992/MAX995/ MAX996 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltage ranges from +2.5V to +5.5V, making them ideal for both 3V and 5V systems. These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 48µA per comparator while achieving a 120ns propagation delay. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals.
