Overview
The MAX5411ETE+T is a dual, logarithmic taper digital potentiometer featuring two wipers per resistor. It replaces mechanical potentiometers in audio applications requiring digitally controlled resistance. The device operates on a single +4.5V to +5.5V supply and includes a zero-crossing detect feature to minimize audible noise during wiper transitions. It utilizes an SPI-compatible serial interface for control and offers a mute function providing -90dB attenuation. The component is housed in a 16-pin thin QFN package and is specified over the extended temperature range of -40°C to +85°C.
Feature Summary
- Dual potentiometers with two wipers each (W0A/W0B, W1A/W1B) and 32-tap positions.
- Logarithmic taper with 2dB steps between taps for audio volume control.
- Zero-crossing detection minimizes audible clicks and pops during switching.
- Mute function achieves -90dB attenuation; Power-On Reset sets wipers to maximum attenuation (-62dB).
Applications
- Stereo Volume Control
- Fading and Balancing Stereo Signals
- Mechanical Potentiometer Replacement
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature range. Ensure that any additional characters in the part number do not alter the functional specifications or pinout configuration before procurement.
Selection Notes
Select the MAX5411ETE+T when dual-channel audio control with independent rear-fade capability is required. This model provides two wipers per resistor, unlike the MAX5410 which has one. Confirm the system operates within the +4.5V to +5.5V supply voltage range and requires a 10kΩ fixed resistance value.
Part Context
This component belongs to the MAX5408–MAX5411 family of dual, audio, log taper digital potentiometers. The MAX5411 specifically distinguishes itself by offering two wipers per potentiometer, enabling complex stereo signal processing such as front/rear fading, whereas other models in the series offer only a single wiper.
Replacement Considerations
The MAX5410ETE+T serves as a direct substitute if only a single wiper per resistor is needed. For lower voltage operation (+2.7V to +3.6V), the MAX5409ETE+T is the compatible alternative within the same family.
