Low Power Stereo Codec with
Headphone Amp
Document Number: SGTL5000
Rev. 6.0, 11/2013
SGTL5000
The SGTL5000 is a Low Power Stereo Codec with Headphone Amp
from Freescale, and is designed to provide a complete audio solution
for products needing LINEIN, MIC_IN, LINEOUT, headphone-out, and
digital I/O. Deriving it’s architecture from best in class, Freescale
integrated products that are currently on the market. The SGTL5000 is
able to achieve ultra low power with very high performance and
functionality, all in one of the smallest footprints available. Target
markets include media players, navigation devices, smart phones,
tablets, medical equipment, exercise equipment, consumer audio
equipment, etc. Features such as capless headphone design and an
internal PLL help lower overall system cost.
AUDIO CODEC
Features
Analog Inputs
• Stereo LINEIN - Support for external analog input
• Stereo LINEIN - Codec bypass for low power
• MIC bias provided
• Programmable MIC gain
• ADC - 85 dB SNR (-60 dB input) and -73 dB THD+N
(VDDA = 1.8 V)
Analog Outputs
• HP Output - Capless design
• HP Output - 62.5 mW max, 1.02 kHz sine into 16 load at 3.3 V
• HP Output - 100 dB SNR (-60 dB input) and -80 dB THD+N
(VDDA = 1.8 V, 16 load, DAC to headphone)
• LINEOUT - 100 dB SNR (-60 dB input) and -85 dB THD+N
(VDDIO = 3.3 V)
Digital I/O
• I2S port to allow routing to Application Processor
Integrated Digital Processing
• Freescale surround, Freescale bass, tone control/ parametric
equalizer/graphic equalizer clocking/control
• PLL allows input of an 8.0 MHz to 27 MHz system clock - standard
audio clocks are derived from PLL
Power Supplies
• Designed to operate from 1.62 to 3.6 volts

Do not connect HP_VGND to system ground, even
when unused. This is a virtual ground (DC voltage) that
should never connect to an actual “0 Volt ground”. Use
the widest, shortest trace possible for the HP_VGND.
