_______________General Description
The MAX394 is a precision, low-voltage, quad, single-
pole/double-throw (SPDT) analog switch. The four inde-
pendent switches operate with bipolar supplies ranging
from ±2.7V to ±8V, or with a single supply of +2.7V to
+15V. The MAX394 offers low on-resistance (less than
35
Ω), guaranteed to match within 2Ω between channels
and to remain flat over the analog signal range (
∆4Ω
max). It also offers break-before-make switching (10ns
typical), with turn-off times less than 75ns and turn-on
times less than 130ns. The MAX394 is ideal for portable
operation since quiescent current runs less than 1µA with
all inputs high or low.
This monolithic, quad switch is fabricated with Maxim’s
low voltage silicon-gate process. Design improvements
guarantee extremely low charge injection (10pC), low
power consumption (10µW), and electrostatic discharge
(ESD) greater than 2000V.
Logic inputs are TTL and CMOS compatible and guaran-
teed over a +0.8V to +2.4V range for supply voltages up
to +8V. When supplies exceed +8V, the inputs are typi-
cally +0.8V to +4V. Logic inputs and switched analog sig-
nals can range anywhere between the supply voltages
without damage.
