0.5Ω, Quad SPDT Switches in UCSP/QFN
General Description
The MAX4754/MAX4754A/MAX4755/MAX4756/MAX4756A
low on-resistance, analog switches operate from a single
+1.8V to +5.5V supply. The MAX4754/MAX4754A and
MAX4755 are dual, double-pole, double-throw (DPDT)
switches. The MAX4756/MAX4756A are quad, single-pole
double-throw (SPDT) switches. They are configured to
route either audio or data signals.
The MAX4754/MAX4754A have four 0.5Ω SPDT switches for
audio-signal routing and two logic control inputs. The
MAX4755 has four 0.5Ω SPDT switches (with two
switches that have an additional 11Ω series resistor at
the NC terminals). This allows users to drive an 8Ω
speaker as a 32Ω load (ear speaker). The MAX4756/
MAX4756A have four 0.5Ω SPDT switches controlled by
one logic control input and an enable input (EN) to dis-
able the switches.
The MAX4754/MAX4754A/MAX4755/MAX4756/MAX4756A
are available in a space-saving 16-pin TQFN and a tiny
16-bump, 2mm x 2mm chip-scale package (UCSP™).
