Overview
The MAX9034ASD+T is a quad comparator in a 14-pin SOIC package. It operates from +2.5V to +5.5V single supplies or ±1.25V to ±2.75V dual supplies. Key electrical parameters include a typical supply current of 35µA per comparator, a maximum propagation delay of 228ns, and an internal hysteresis of 4mV. The input common-mode range extends from the negative supply to within 1.1V of the positive supply. The device features rail-to-rail push-pull outputs and guarantees operation across a temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-rail output stage that swings fully to supply rails while reducing switching current to minimize power-supply glitches.
- Internal 4mV hysteresis provides noise immunity and prevents oscillations during slow-moving input signal transitions.
- Input common-mode voltage range extends from the negative supply to within 1.1V of the positive supply.
- No phase reversal occurs for overdriven inputs, ensuring stable operation under extreme conditions.
Applications
- Battery-powered portable systems
- Mobile communications equipment
- Sensor signal detection circuits
- Photodiode preamplifier interfaces
- Digital line receivers
Procurement Notes
Verify the 'T' suffix indicates tape-and-reel packaging rather than tube. Confirm the 'SD' designation corresponds to the 14-pin SOIC package variant. Ensure the '+/' lead-free/RoHS compliance status matches project requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity before procurement.
Selection Notes
Select this component when four independent comparators are required in a compact surface-mount footprint. It is suitable for applications demanding low quiescent current and high noise immunity without external feedback components. Verify that the 1.1V headroom requirement at the positive supply rail accommodates the specific input signal levels of the target design.
Part Context
This device belongs to the MAX903x family of ultra-small, low-cost single-supply comparators manufactured by Maxim Integrated, now part of Analog Devices. The MAX9034 specifically integrates four channels, contrasting with the single-channel MAX9030/MAX9031 and dual-channel MAX9032 variants within the same series.
