MAX9830

The MAX9830 is available in an 8-pin TDFN (2mm x 2mm x 0.8mm)and is specified over the extended -40°C to +85°C temperature range. The MAX9830's industry-leading 1.6mA at 5V, 1.2mA at 3.6V, quiescent current extends battery life in portable applications. The MAX9830 mono 2W Class D amplifier provides Class AB audio performance with Class D efficiency. Active emissions limiting edge rate and overshoot control circuitry greatly reduces EMI. A filterless spreadspectrum modulation scheme eliminates the need for output filtering found in traditional Class D devices. These features reduce application component count.

The features of MAX9830 can be summarized as (1)industry-leading quiescent current: 1.6mA at 5V, 1.2mA at 3.6V; (2)spread spectrum and active emissions limiting; (3)passes EMI limit unfiltered with up to 24in (61cm)of speaker cable; (4)click-and-pop suppression; (5)thermal and overcurrent protection; (6)low 0.5A current shutdown mode; (7)space-saving, 2mm x 2mm x 0.8mm, 8-Pin TDFN Package.

The absolute maximum ratings of MAX9830 are (1)voltage PVDD, IN+, IN-, SHDN, to PGND: -0.3V to +6V/ OUT+, OUT- to PGND: -0.3V to VPVDD + 0.3V; (2)current continuous current Into/Out of PVDD, PGND, OUT+, OUT-: ±600mA/ Continuous Input Current (all other pins): ±20mA; (3)duration of short circuit between OUT+, OUT-, and PVDD, PGND: Continuous; (4)continuous power dissipation for a multilayer board (TA = +70°C)8-Pin TDFN-EP (derate 11.9mW/°C): 953.5mW; (5)junction temperature: +150°C; (6)operating temperature range: -40°C to +85°C; (7)storage temperature range: -65°C to +150°C; (8)lead temperature (soldering, 10s): +300°C; (9)Soldering Temperature (reflow): +260°C; (10)rate of voltage rise at PVDD: 1V/s.
