The LT1671 is a low power 60ns comparator with complementary outputs and latch. The input common mode range extends from 1.5V below the positive supply down to the negative supply rail. Like the LT1394, LT1016 and LT1116, this comparator has complementary outputs designed to interface directly to TTL or CMOS logic. The LT1671 may operate from either a single 5V supply or dual ±5V supplies. Low offset voltage specifications and high gain allow the LT1671 to be used in precision applications.

The LT1671 is designed for improved speed and stability for a wide range of operating conditions. The output stage provides active drive in both directions for maximum speed into TTL, CMOS or passive loads with minimal cross-conduction current. Unlike other fast comparators, the LT1671 remains stable even for slow transitions through the active region, which eliminates the need to specify a minimum input slew rate.

The LT1671 has an internal, TTL/CMOS compatible latch for retaining data at the outputs. The latch holds data as long as the LATCH pin is held high. Device parameters such as gain, offset and negative power supply current are not significantly affected by variations in negative supply voltage.

Applications

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)
