Overview
The MAX901BESE+T is a high-speed, low-power quad voltage comparator from the MAX900–MAX903 series. It features four independent channels with differential analog inputs and TTL-logic outputs equipped with active internal pull-ups. The device operates on separate analog and digital supplies or a single combined supply, supporting flexible analog voltages from +5V to +10V or ±5V. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 2mV maximum input offset voltage, and 6µA input bias current. Power consumption is approximately 18mW per comparator at +5V.
Feature Summary
- Features fast propagation delay for high-speed data discrimination applications
- Provides TTL-compatible outputs with active internal pull-ups
- Supports flexible analog supply ranges including single and split configurations
- Allows ground sensing when powered from a single supply due to negative rail input range
Applications
- High-speed A/D converters
- Sampling circuits
- Line receivers
- Voltage-to-frequency (V/F) converters
- Data-discrimination applications
Procurement Notes
Verify the specific suffix 'E' indicates the industrial temperature range of -40°C to +85°C and 'S' denotes the SOIC package. Confirm '+T' signifies tape-and-reel packaging. Ensure compatibility with existing designs as this component is not recommended for new designs; consult technical support for replacement options if required.
Selection Notes
Select the MAX901BESE+T when four independent comparators are needed without latch functionality. Choose this part over MAX900/MAX902/MAX903 variants if latch inputs are unnecessary. Consider the SOIC package for surface-mount assembly. Verify power supply requirements match the +5V to +10V analog range and +5V digital supply constraints.
Part Context
The MAX901BESE+T belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices / Maxim Integrated. This family includes quad (MAX900/MAX901), dual (MAX902), and single (MAX903) channel devices. The MAX901 specifically provides quad performance but lacks the latch inputs found in other family members.
Replacement Considerations
The datasheet notes that the MAX900 was manufactured using a process no longer available and is not recommended for new designs. For newer pin-for-pin compatible parts with similar speed but lower power dissipation, refer to the MAX9201/MAX9202/MAX9203 data sheet.
