PI5A4765
Low Voltage Dual SPDT Audio Clickless Analog Switch
with Headphone/Mute Detection
2:1 Mux/DeMux Bus Switch
Description
Pericom Semiconductors PI5A4765 is a dual high-bandwidth,
fast single-pole double throw (SPDT) CMOS switch. It can be
used as an analog switch or as a low-delay bus switch. Specified
over a wide operating power supply voltage, 1.65V to 5.5V, the
PI5A4765 has a low On-Resistance of 0.6 @ 2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching. The control input, INX, tolerates input drive signals up
to 6.0V, independent of supply voltage.
The PI5A4765 offers a headphone & mute detection function
through utilization of an on-chip comparator. When the negative
terminal of the comparator (COMP-) is less than the threshold
(internally set to VCC/3, COMP0 (comparator output) is a logic
high. A logic low on COMP0 occurs when COMP- rises above
the the threshold.
PI5A4765 also offers shunt switches connected to ground in order
to dissipate capacitance that builds up on the unconnected NC or
NO line. As a result, reduction of popping and clicking sounds is
achieved when switching between audio sources.
