Dual SPST Analog Switches in UCSP
General Description
The MAX4721/MAX4722/MAX4723 low-voltage, low on-
resistance (R
ON
), dual 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 MAX4721/MAX4722/MAX4723 feature 4.5Ω R
ON
(max) with 1.2Ω flatness and 0.3Ω 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 compati-
ble 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 1.52mm
1.52mm area
and has a 3
3 bump array with a bump pitch of
0.5mm. These switches are also available in an 8-pin
µMAX package.
