TPA3128D2 – 2 x 30/50W Stereo 60/100W Mono Class-D Verstärker

With the TPA3128D2 Texas Instruments introduces a successor of TPA3118D2 , which combines the advantages of 1SPW and BD modulation in a hybrid mode. Beside this, the output stage was revised (90mR = Rds_on vs. 120mR) and also the minimum permissible operating voltage were lowered. As low as 4.5V is possible. He follows in the footsteps of the previous "perennial" TPA3118D2 as well as TPA3116D2. (The TPA3116D2 will now be superseded by the TPA3156D2 )

Specs are:

  • Differential analog inputs 2Vrms
  • Efficiency 90% (4 ohms)
  • 4.5-26V Supply voltage
  • Gain: 20dB, 26dB, 32dB, 36dB
  • 2 x 40W at 8 Ohm BTL (24V, 10% THD)
  • 2 x 70W at 4 Ohm BTL (24V, 10% THD)
  • 105W at 2 Ohm PBTL (22V, 10% THD)
  • 2 x 35W at 8 Ohm BTL (24V, 1% THD)
  • 2 x 57W at 4 Ohm BTL (24V, 1%THD)
  • 90W at 2 Ohm PBTL (22V, 1%THD)
  • Possible configuration: Stereo (2 x BTL), Mono (1xBTL), Mono (PBTL)
  • 300-1200kHz switching frequency
  • Adaptive Modulation (Hybrid Mode)
  • 70dB PSRR, <65uV output noise, >102dB SNR
  • BD or 1SPW Modulation
  • Integrated LDO and 5V gate-drive supply
  • HTSSOP32
