MAX9716EBL+TG45

Audio Amplifiers Overview

The MAX9716EBL+TG45 is a mono audio power amplifier from the MAX9716 series, designed for portable devices with internal speakers. It utilizes a bridge-tied load (BTL) architecture to deliver 1.4W continuous power into a 4Ω load at 1% THD+N and 1W into an 8Ω load when operating from a single +5V supply. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It features adjustable gain, low-power shutdown mode reducing quiescent current to less than 10nA, and comprehensive click-and-pop suppression. The component is housed in a 3mm x 3mm UCSP package.

Audio Amplifiers Feature Summary

• Bridge-tied load (BTL) architecture minimizes external component count while providing high-quality audio reproduction.
• Industry-leading click-and-pop suppression reduces audible artifacts during startup and shutdown.
• Low-power shutdown mode disables bias generators and amplifiers to minimize current consumption.
• Adjustable gain configuration allows flexibility in circuit design without fixed internal resistors.

Audio Amplifiers Applications

• Mobile phones
• Personal digital assistants (PDAs)
• Portable audio devices

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix G45 indicates protective die coating as per manufacturer documentation. Confirm the package type matches the required 3mm x 3mm UCSP footprint. Ensure compatibility with the -40°C to +85°C extended temperature range specified for this part number. Cross-reference the exact part number against official distributor databases to confirm availability status and lead times.

Audio Amplifiers Selection Notes

Select this component for applications requiring a compact mono amplifier with BTL output. The adjustable gain feature distinguishes it from fixed-gain variants within the same family. Consider the thermal dissipation requirements of the UCSP package under maximum power conditions. Verify that the input signal interface aligns with the differential or single-ended input capabilities of the MAX9716 variant.

Audio Amplifiers Part Context

This part belongs to the MAX9716/MAX9717 family of low-cost, mono, 1.4W BTL audio power amplifiers. The MAX9716 specifically offers adjustable gain, whereas other members like the MAX9717 include additional features such as headphone sense inputs. The family is optimized for battery-powered portable electronics where space and power efficiency are critical constraints.

Audio Amplifiers Replacement Considerations

The MAX9716 is pin-compatible with the LM4890. Designers may consider the LM4890 as a direct replacement if sourcing the MAX9716EBL+TG45 is difficult, provided the application does not require specific Maxim Integrated performance characteristics.
