E s W E DATASHEET Tempo Semiconductor, Inc. PORTABLE CONSUMER CODEC TSDP11xx / TSDP10xx CLASS-H DIRECTCONNECT HEADPHONE AMPLIFIER DESCRIPTION FEATURES The TSDP11xx and TSDP10xx devices are Class-H architecture Class-H Capless DirectConnect Technology Capless DirectConnect Ground-Referenced Output Headphone Eliminates Large Output DC Blocking Capacitors stereo amplifiers with GPIO shutdown control. The TSDP11xx Reduces Board Area provides independent left / right channel volume control, mute and Reduces Component Height and Cost fine parameter adjustment via the two-wire I2C compatiable serial Enables Full Bass Response Without Attenuation interface. Both provide high-quality audio fidelity with an SNR / Offers No Pop on Start-Up or Power-Down DNR of up to 106dB, a THD+N as low as -85dB, an output power Reduces Power consumption by as much as 45% at of up to 170mW per channel into 16 or up to 2Vrms into a 10K. Typical Listening Levels compared to Class A/B The differential inputs allow for flexible input configuration that solutions maximizes noise rejection for best-in-class CMRR that exceeds < 1uA Shutdown Supply Current the competition by up to 21dB. < 1uA Shutdown Input Leakage Current Up to 170mW Per Channel into 16 TARGET APPLICATIONS Up to 106dB SNR / DNR (10K) Charge-pump allows for True Ground Centered Outputs Gaming-Class Motherboards High Power Supply Rejection Ratio (>100 dB PSRR) Differential Inputs for Maximum Noise Rejection Ratio Tablet Computers (90 dB CMRR) Gaming-class Laptops Optional register controlled High-Impedance Outputs Portable Gaming Platforms When Disabled Independent Left/Right Volume and Mute Control Digital Audio Streaming / Connected Audio (TSDP11xx) Accessories Power Supply Voltage Range: 2.5 V to 5.5 V Bluetooth-enabled Headphones / Headsets / GPIO Control for Hardware Shutdown Advanced Features Control via Register setting over Docking Stations / Adapters I2C, including Low-Power Mode Support (TSDP11xx) Wi-Fi (Miracast, Chromecast, AirPlay 2)-enabled Compact 20-Pin, 4mm x 4mm QFN RoHS Package Headphones / Headsets Offerings in both Commercial and Industrial Temp Ranges offered in either Tray or Tape & Reel Lightning-enabled Headphones / Headsets / Docking Stations / Adapters TSDP11XX BLOCK DIAGRAM Thunderbolt I/II/III-enabled Headphones / Headsets / Docking Stations / Connectivity ,QWHUQDO Expansion Hubs / Adapters 2VFLOODWRU HDMI-enabled VR / AR / MR Headphones and > +3B5 Headsets MHL-enabled VR / AR / MR Headphones and Headsets W USB 1.1 / 2.0 / 3.0 / 3.1 Gen 1 / 3.1 Gen 2 / USB-C-enabled Headphones / Headsets / Docking Z +3B/ Stations / Connectivity Expansion Hubs / Tablets / Mobile Phones / Tablet & Mobile Phone Cases / Portable Projectors &XUUHQW Remote Controls / Gaming Controllers with 7KHUPDO /LPLW Headphone Jacks WW , & ,QWHUIDFH WE 6KXWGRZQ W D &RQWURO sZ > s s 1 V1.5 6/18/2018 2018 TEMPO SEMICONDCUTOR, INC.
