Detailed Description
The ISL99202 incorporates a novel proprietary architecture
to eliminate the large output capacitors associated with
single supply headphone amplifiers. Traditional charge
pump based architectures that eliminated the output
capacitors required additional power to operate the charge
pump, which made them ill-suited for portable battery
powered applications. The ISL99202 architecture eliminates
the need for large output capacitors while consuming
industry’s lowest quiescent and shutdown currents.
Capfree Architecture
At the core of the Capfree architecture is a dynamically
adjusted negative voltage regulator. By continuously
monitoring the output power requirements, it adjusts the
energy delivery circuitry. The feedback system ensures that
overhead power required to deliver audio at the headphone
speaker is always optimized for lower power dissipation.
Integrated LDO
A high precision LDO integrated into the power path of the
amplifier accounts for a 92dB PSRR. This eliminates the
need for a dedicated LDO used in some systems resulting in
BOM/cost savings.
Offset Cancellation Circuitry
The DC offset is a very important parameter. It is a principal
contributor to Click and Pop. In the cast Capfree
architecture, the DC offset can also be a source of DC
current in quiescent state. The ISL99202 is tested and
trimmed to have very low offset voltages (typically 50V).
RF Immunity
Most portable applications for ISL99202 are subject to RF
radiation from a myriad of sources, like Wi-Fi networks or
cellular phone networks. Though these signals are not in the
audio band, they can interfere with the audio signals through
complex non-linear mechanisms, aliasing or demodulations
to create audio band noise. The ISL99202 architecture
prevents this coupling into audio band to achieve superior
audio performance.
Protection Circuitry
The ISL99202 has comprehensive protection circuitry, which
protects the part due to undervoltage, over-temperature and
overcurrent. There is hysteresis built into over-temperature
and undervoltage, while the overcurrent is designed to limit
the output current in case of accidental short circuit or low
impedance headphone load connection.
