General Description
Maxim’s DG300–DG303 and DG300A–DG303A CMOS
dual and quad analog switches combine low power
operation with fast switching times and superior DC and
AC switch characteristics. On-resistance is less than
50Ωand is essentially constant over the analog signal
range. Device specifications are ideal for battery-
powered circuitry.
These switches are available in a variety of formats as
outlined in the Pin Configurations section. The switch
control logic inputs are fully TTL and CMOS compati-
ble. Also featured are “break-before-make” switching
and low charge injection.
Maxim’s DG300-DG303 and DG300A-DG303A families
are electrically compatible and pin compatible with the
original manufacturer’s devices. All devices operate with
power supplies ranging from ±5V to ±18V. Single-sup-
ply operation is implemented by connecting V- to GND.

Note 1: Signals on SX, DX, or INXexceeding V+ or V- are clamped by internal diodes. Limit diode forward current to maximum cur-

Note 2: The algebraic convention whereby the most negative value is a minimum, and the most positive value is a maximum is used
in this data sheet.
Note 3: Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

Applications Information
All DG300 family switches will operate with ±5V to ±15V
power supplies. They can also be used with single-ended
power supplies ranging from +10V to +30V where the V-
terminal is connected to ground. In either case, analog
signals ranging from V+ to V- can be switched.
The on-resistance variation with analog signal and supply
voltage is shown in the Typical Operating Characteristics.
The temperature coefficient of RON is typically 0.5%/°C.
Typical on-resistance matching from channel to chan-
nel is 10%. In addition, Table 1 outlines some typical
parameters for single-supply operation.
The charge injection test circuit is shown in Figure 1.
Table 2 lists the typical injected charge for DG300 series
switches with various input voltages.
