MAX4335–MAX4338
SC70/SOT23-8, 50mA IOUT, Rail-to-Rail I/O
Op Amps with Shutdown/Mute
12
______________________________________________________________________________________
Figures 8 and 9 show the transient response with
excessive capacitive loads (330pF), with and without
the addition of an isolation resistor in series with the
output. Figure 10 shows a typical noninverting capaci-
tive-load-driving circuit in the unity-gain configuration.
The resistor improves the circuit’s phase margin by iso-
lating the load capacitor from the op amp’s output.
Power-Up and Shutdown/Mute Modes
The MAX4336/MAX4338 have a shutdown option.
When the shutdown pin (SHDN) is pulled low, supply
current drops to 0.04A per amplifier (VCC = 5V), the
amplifiers are disabled, and their outputs are placed in
a high-impedance state. Pulling SHDN high enables
the amplifier. In the dual MAX4338, the two amplifiers
shut down independently. Figure 11 shows the
MAX4336’s output voltage response to a shutdown
pulse. The MAX4335–MAX4338 typically settle within
5s after power-up (Figure 12).
Power Supplies and Layout
The MAX4335–MAX4338 can operate from a single
2.7V to 5.5V supply. Bypass the power supply with a
0.1F ceramic capacitor in parallel with at least 1F.
Good layout improves performance by decreasing the
amount of stray capacitance at the op amps’ inputs
and outputs. Decrease stray capacitance by placing
external components close to the op amps’ input/output
pins, minimizing trace and lead lengths.
Thermal Overload Protection
The MAX4335–MAX4338 includes thermal overload
protection circuitry. When the junction temperature of
the device exceeds +140°C, the supply current drops
to 120A per amplifier (VCC = 5V) and the outputs are
placed in a high-impedance state. The device returns
to normal operation when the junction temperature falls
to below +120°C.
Short-Circuit Current Protection
The MAX4335–MAX4338 incorporate a smart short-cir-
cuit protection feature. Figure 7 shows the output volt-
age region where the protection circuitry is active. A
fault condition occurs when IOUT > 110mA and VOUT >
1V (sinking current) or when IOUT > 110mA and (VCC -
VOUT) > 1V (sourcing current). When a fault is detect-
ed, the short-circuit protection circuitry is activated and
the output current is limited to 110mA, protecting the
device and the application circuitry. When the smart
short circuit is not active, the output current can safely
exceed 110mA (see the Output Current vs. Output
Voltage Graph in the Typical Operating Characteristics).
