4.5Ω Quad SPST Analog Switches in UCSP
General Description
The MAX4737/MAX4738/MAX4739 low-voltage, low on-
resistance (R_ON), quad single-pole/single throw (SPST)
analog switches operate from a single +1.8V to +5.5V
supply. These devices are designed for USB 1.1 and
audio switching applications.
The MAX4737/MAX4738/MAX4739 feature 4.5Ω R_ON
(max) with 1.2Ω flatness and 0.4Ω matching between
channels. These new switches feature guaranteed
operation from +1.8V to +5.5V and are fully specified
at 3V and 5V. These switches offer break-before-make
switching (1ns) with t_ON <80ns and t_OFF <40ns at +2.7V.
The digital logic inputs are +1.8V logic compatible with a
+2.7V to +3.6V supply.
These switches are packaged in a chip-scale package
(UCSP™), significantly reducing the required PC board
area. The chip occupies only a 2mm x 2mm area and has
a 4 x 4 bump array with a bump pitch of 0.5mm. These
switches are also available in a 14-pin TSSOP and a
16-pin thin QFN (4mm x 4mm) package.
