Overview
The MAX9034AUD+T is a quad comparator in a 14-pin TSSOP package. It operates from +2.5V to +5.5V single supply or ±1.25V to ±2.75V dual supplies. The device features a 188ns propagation delay and consumes 35µA per comparator. Input offset voltage is typically ±1mV with internal 4mV hysteresis. Common-mode range extends from VSS to VDD-1.1V. Output swings rail-to-rail without phase reversal.
Feature Summary
- Quad configuration with rail-to-rail output capability
- Internal 4mV hysteresis for noise immunity
- Low power consumption of 35µA per channel
- No phase reversal for overdriven inputs
Applications
- Battery-powered portable systems
- Mobile communications devices
- Sensor signal detection circuits
- Photodiode preamplifier interfaces
- Digital line receivers
Procurement Notes
Verify the suffix 'T' indicates tape and reel packaging. Confirm the '+D' suffix corresponds to the 14-pin TSSOP physical footprint. Ensure the '+T' designation aligns with specific handling requirements for automated surface-mount assembly processes during procurement.
Selection Notes
Select this component when four independent comparators are required in a compact form factor. The low supply current makes it suitable for battery-operated designs. Verify that the 188ns propagation delay meets system timing constraints. Ensure the input common-mode range accommodates the specific signal levels present in the application circuit.
Part Context
This part belongs to the MAX903x family, which includes single (MAX9030), dual (MAX9031), and quad (MAX9034) variants. The MAX9034 specifically provides four channels in a 14-pin TSSOP package. Other family members offer different pin counts and package types such as SC70 and SOT23.
Replacement Considerations
The MAX9034ASD+ serves as a direct functional replacement using a 14-pin SOIC package instead of TSSOP. Both parts share identical electrical characteristics and pinouts. Verify mechanical clearance allows for the alternative package width before substitution.
FAQ
Does the MAX9034 have a shutdown mode?
No, the MAX9034 does not include a shutdown pin. Only the MAX9030 variant in the family features a shutdown function.
What is the input common-mode voltage range?
The input common-mode range extends from the negative supply (VSS) to within 1.1V of the positive supply (VDD).
