TTL Compatible CMOS Analog Switches
Features
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
50Ω and is essentially constant over the analog signal
range. Device specifications are ideal for batterypowered circuitry.
♦ Monolithic Low-Power CMOS
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 compatible. 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-supply operation is implemented by connecting V- to GND.
♦ V+ to V- Analog Signal Range
Applications
♦ Latchup Proof Construction
♦ Fully Compatible 2nd Source
♦ Low On-Resistance, <50Ω
♦ Fast Switching Time
♦ Single-Supply Capability

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 Vterminal 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 channel is 10%. In addition, Table 1 outlines some typical
parameters for single-supply operation.
