CLASS-H DIRECTCONNECT™ HEADPHONE AMPLIFIER
TSDP11xx / TSDP10xx
DESCRIPTION
FEATURES
The TSDP11xx and TSDP10xx devices are Class-H architecture
Capless DirectConnect Ground-Referenced Output Headphone
stereo amplifiers with GPIO shutdown control. The TSDP11xx
provides independent left / right channel volume control, mute and
fine parameter adjustment via the two-wire I2C compatiable serial
interface. Both provide high-quality audio fidelity with an SNR /
DNR of up to 106dB, a THD+N as low as -85dB, an output power
of up to 170mW per channel into 16Ω or up to 2Vrms into a 10KΩ.
The differential inputs allow for flexible input configuration that
maximizes noise rejection for best-in-class CMRR that exceeds
the competition by up to 21dB.
