Overview
The MAX902EPD+ is a dual-channel high-speed voltage comparator housed in a 14-pin Plastic DIP package. It features TTL-logic outputs with active internal pull-ups and independent latch inputs for state holding. The device operates from separate analog and digital supplies or a single combined supply, supporting an analog range of +5V to +10V or ±5V. Typical propagation delay is 8ns at 5mV overdrive, with power consumption of 18mW per comparator at +5V. Input offset voltage is typically 4mV, and input bias current is 10µA.
Feature Summary
- Features independent TTL-compatible latch inputs that hold the comparator output state when driven low.
- Provides flexible analog supply options including single +5V to +10V or split ±5V configurations.
- Analog input common-mode range includes the negative rail, enabling ground sensing on single-supply systems.
- Delivers fast propagation delay suitable for high-speed data discrimination applications.
Applications
- High-speed A/D converters
- Sampling circuits
- Line receivers
- Voltage-to-frequency (V/F) converters
Procurement Notes
Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range and 'PD' indicates the 14-pin Plastic DIP package. Confirm RoHS compliance status as datasheets may vary by revision. Check for Not Recommended for New Designs notices regarding legacy manufacturing processes associated with this family.
Selection Notes
Select the MAX902EPD+ for designs requiring dual comparators with latching capability and TTL-compatible outputs. Ensure the application supports the required analog supply voltage range of +5V to +10V or ±5V. Consider the 8ns propagation delay and 18mW power dissipation per channel against system speed and thermal constraints.
Part Context
The MAX902EPD+ belongs to the MAX900–MAX903 series of high-speed, low-power voltage comparators manufactured by Analog Devices / Maxim Integrated. This series is characterized by differential analog inputs and fast response times. The MAX902 specifically provides two channels with latch functionality, distinguishing it from the non-latch MAX901.
Replacement Considerations
The datasheet notes the part is not recommended for new designs due to unavailable foundry processes. For newer pin-for-pin compatible parts with half the power dissipation, consult the MAX9201/MAX9202/MAX9203 data sheet.
