The ADCMP391 / ADCMP392 / ADCMP393 are single/dual/quad rail-to-rail input, low power comparators ideal for use in general-purpose applications. These comparators operate from a single supply voltage of 2.3 V to 5.5 V and draw a minimal amount of current. The single ADCMP391 consumes only 18.6 µA of supply current. The dual ADCMP392 and the quad ADCMP393 consumes 22.1 µA and 26.8 µA of supply current, respectively. The low voltage and low current operation of these devices makes it ideal for battery-powered systems.

The comparators features a common-mode input voltage range of 200 mV beyond rails, an offset voltage of 1 mV typical across the full common-mode range, and a UVLO monitor. In addition, the design of the comparators allows a defined output state upon power-up, a logic low output while the supply voltage is less than the UVLO threshold.

The ADCMP391 and ADCMP392 are available in 8-lead, narrow body SOIC package while the ADCMP393 is available in a 14-lead, narrow body SOIC package and a 14-lead TSSOP package. The comparators are specified to operate over the −40°C to +125°C extended temperature range.

EVAL-ADCMP396

ADCMP396 Evaluation Board

ADCMP396 Evaluation Board

Features and Benefits

  • Positive and negative voltage monitoring
  • LED indicated voltage output status
  • Test points for easy probing

Product Detail

Customers of ADCMP391/ADCMP392/ADCMP393/ADCMP394/ADCMP395 comparators may evaluate the performance of these devices using ADCMP396, which has near identical electrical performance to this part and contains a superset of functions featured by this device family.

The EVAL-ADCMP396EBZ features accurate positive and negative voltage monitoring with 0.9% accuracy. The evaluation board uses LEDs to indicate an overvoltage or undervoltage event in both positive and negative voltage being monitored.


The ADCMP396 is a quad rail-to-rail input low power comparator suitable for general-purpose applications. The ADCMP396 consumes only 41.61 μA of supply current making it ideal for battery-powered systems.

The ADCMP396 has a common-mode input range of 200 mV beyond rails, a typical offset voltage of 1 mV across the full common-mode range, and an undervoltage lockout (UVLO) monitor. In addition, the design of the comparator allows a defined output state upon power-up, it generates a logic low output while the supply is still below the UVLO threshold.

The ADCMP396 incorporates a 1 V ± 0.9% buffered reference voltage over line, load, and temperature.

ADALM-SR1

Switching Regulator Active Learning Module

Switching Regulator Active Learning Module

Features and Benefits

  • Companion module for Active Learning labs on buck and boost power converters
  • Illustrates important concepts related to buck and boost converters:
    • Continuous vs. Discontinuous Conduction Modes
    • Open loop operation
    • Voltage mode control
    • Current mode control
  • Independently adjustable parameters: frequency, duty cycle, voltage/current mode
  • Onboard current sense amplifiers and adjustable load minimize equipment requirements.

Product Detail

The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:

  • Boost and Buck converter elements and open-loop operation
  • Buck Converters: closed loop operation
  • Boost Converters: closed loop operation

The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:

  • 5V USB wall adapter
  • Basic adjustable power supply for input power (0-12V, 2A)
  • Multimeter
  • ADALM2000 or basic oscilloscope (2 channels with trigger, >10MHz bandwidth)
