INA302 - Current-Sense Amplifiers

General Description

The INA302 and INA303 (INA30x) devices feature a high common-mode, bidirectional, current-sensing amplifier and two high-speed comparators to detect out-of-range current conditions.

The INA302 comparators are configured to detect and respond to overcurrent conditions.

Key Features

  • 1 Wide common-mode input range:.
  • 0.1 V to +36 V.
  • Dual comparator outputs:.
  • INA302: Two independent overlimit alerts.
  • INA303: Window comparator.
  • Threshold levels set individually.
  • Comparator 1 alert response: 1 µs.
  • Comparator 2 adjustable delay: 2 µs to 10 s.
  • Open-drain outputs with independent latch control modes.
  • High accuracy amplifier:.
  • Offset voltage: 30 µV (max, A3 version).
  • Offset vol.
