MAX4448ESE

Video Amps And Modules Overview

The MAX4448ESE is a single-ended-to-differential line driver designed for high-speed communications. It features a small-signal bandwidth of 330MHz and a slew rate of 4300V/µs. The device delivers an output current drive of 130mA and operates on supply voltages ranging from ±4.5V to ±5.5V with a quiescent current of 46mA. It includes a low-power enable mode that reduces current consumption below 5.5mA. The component is housed in a 16-pin Narrow SO package.

Video Amps And Modules Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature range of -40°C to +85°C. Confirm the package type matches the 16-pin Narrow SOIC footprint. Check for RoHS compliance status as indicated by the '+' suffix. Ensure the ordering information aligns with the manufacturer's current product lifecycle status.

Video Amps And Modules Selection Notes

Select this component when a fixed minimum gain of +2V/V is required with adjustable gain capabilities. It is suitable for applications needing high output drive current and wide bandwidth. Consider the enable pin functionality if power management during idle states is necessary. Verify compatibility with the system's supply voltage requirements.

Video Amps And Modules Part Context

This part belongs to the MAX4447/MAX4448/MAX4449 family of wideband line drivers. While sharing similar architectures, the MAX4448 differs from the MAX4447 which has a fixed +2V/V gain and higher bandwidth, and the MAX4449 which offers higher slew rates and different gain configurations. All variants utilize the same 16-pin Narrow SO package.

Video Amps And Modules FAQ

How is the gain configured for the MAX4448?

The gain is set using an external resistor connected between the RG pin and ground. The formula is Gain = 2(1 + 300/RG), allowing for variable gain selection with a minimum stable gain of +2V/V.

What is the function of the EN pin?

The EN pin is an active-high, TTL-compatible enable input. When driven high, the device operates normally; when driven low, it enters a low-power mode with reduced current consumption and high-impedance outputs.
