DESCRIPTION
PCM1770, PCM1771
SLES011E – SEPTEMBER 2001 – REVISED MARCH 2007
LOW-VOLTAGE AND LOW-POWER STEREO AUDIO DIGITAL-TO-ANALOG CONVERTER
WITH HEADPHONE AMPLIFIER
• Portable Audio Player
• Multilevel DAC Including Headphone Amplifier
• Cellular Phone
• Analog Performance (V
CC, VHP = 2.4 V):
• PDA
Dynamic Range: 98 dB Typ
• Other Applications Requiring Low-Voltage
THD+N at 0 dB: 0.1% Typ
Operation
THD+N at –20 dB: 0.04% Typ
Output Power at RL = 16 Ω: 13 mW
(Stereo), 26 mW (Monaural)
The PCM1770 and PCM1771 devices are CMOS,
• 1.6-V to 3.6-V Single Power Supply
monolithic, integrated circuits which include stereo
• Low Power Dissipation: 6.5 mW at V
CC, VHP =
digital-to-analog converters, headphone circuitry, and
support circuitry in small TSSOP-16 and VQFN-20
2.4 V
packages.
• System Clock: 128 f
S, 192 fS, 256 fS, 384 fS
The data converters use TI's enhanced multilevel
∆-Σ
• Sampling Frequency: 5 kHz to 50 kHz
architecture, which employs noise shaping and
• Software Control (PCM1770):
multilevel amplitude quantization to achieve excellent
16-, 20-, 24-Bit Word Available
dynamic performance and improved tolerance to
clock jitter. The PCM1770 and PCM1771 devices
Left-, Right-Justified, and I2S
accept several industry standard audio data formats
Slave/Master Selectable
with 16- to 24-bit data, left-justified, I2S, etc.,
Digital Attenuation: 0 dB to –62 dB, 1
providing easy interfacing to audio DSP and decoder
dB/Step
devices. Sampling rates up to 50 kHz are supported.
A
full
set
of
user-programmable
functions
is
44.1-kHz Digital De-Emphasis
accessible through a 3-wire serial control port, which
Zero Cross Attenuation
supports register write functions.
Digital Soft Mute
Monaural Analog-In With Mixing
Monaural Speaker Mode
• Hardware Control (PCM1771):
Left-Justified and I2S
44.1-kHz Digital De-Emphasis
Monaural Analog-In With Mixing
• Pop-Noise-Free Circuit
• 3.3-V Tolerant
• Packages: TSSOP-16 and VQFN-20
