MAX98300

Description

The MAX98300 is available in an 8-pin TDFN-EP (2mm x 2mm x 0.8mm)and a 9-bump (1.2mm x 1.2mm)WLP. Both packages are specified over the extended -40°C to +85°C temperature range. The MAX98300 mono 2.6W Class D amplifier provides Class AB audio performance with Class D efficiency. These features reduce application component count. The MAX98300 industry-leading 0.78mA at 3.7V (1.1mA at 5V)quiescent current extends battery life in portable applications. This device offers five selectable gain settings (0dB, 3dB, 6dB, 9dB, and 12dB)set by a single gain-select input (GAIN). Active emissions-limiting edge-rate and overshoot con- trol circuitry greatly reduces EMI. A patented filterless spread-spectrum modulation scheme of MAX98300 eliminates the need for output filtering found in traditional Class D devices.

The features of MAX98300 can be summarized as (1)industry-leading quiescent current: 0.78mA at 3.7V, 1.1mA at 5V; (2)spread spectrum and active emissions limiting; (3)five selectable gains; (4)click-and-pop suppression; (5)thermal and overcurrent protection; (6)low-current shutdown mode; (7)space-saving packages 2mm x 2mm x 0.8mm, 8-Pin TDFN-EP/ 1.2mm x 1.2mm, 9-Bump WLP (0.4mm Pitch).

The absolute maximum ratings of MAX98300 are (1)PVDD, IN+, IN-, SHDN, GAIN to PGND: -0.3V to 6V; (2)all other pins to PGND: -0.3V to (VPVDD + 0.3V); (3)continuous current into/out of PVDD, PGND, OUT_: Q600mA; (4)continuous input current (all other pins): Q20mA; (5)duration of short circuit between OUT_ and PVDD, PGND: Continuous/ OUT+ and OUT-: continuous; (6)continuous power dissipation (TA = +70°C)for multilayer board TDFN-EP (derate 11.9mW/°C): 953.5mW/ WLP (derate 12mW/°C): 963.8mW; (7)junction temperature: +150°C; (8)operating temperature range: -40°C to +85°C; (9)storage temperature range: -65°C to +150°C; (10)lead temperature (soldering, 10s): +300°C; (11)soldering temperature (reflow): +260°C.
