MAXIM MAX4754, MAX4754A, MAX4755, MAX4756, MAX4756A User Manual

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 disable 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™).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
