Single/Dual SC70, Zero-Drift,
High-Efficiency, 1.5MHz Op Amps with RRIO
General Description
Features
The MAX9617–MAX9620 are low-power, zero-drift oper-
ational amplifiers available in space-saving SC70 pack-
ages. They are designed for use in portable consumer,
medical, and industrial applications.

Very-Low 10µV (max) Input Offset Voltage
Dual Version Available in an 8-Pin SC70 Package
Low Input Noise
The MAX9617–MAX9620 feature rail-to-rail CMOS inputs
and outputs, a 1.5MHz GBW at just 59FA supply current
and 10FV (max) zero-drift input offset voltage over time
and temperature. The zero-drift feature reduces the high
1/f noise typically found in CMOS input operational ampli-
fiers, making it useful for a wide variety of low-frequency
measurement applications.

Detailed Description
The MAX9617–MAX9620 are precision, low-power op
Shutdown Operation
The MAX9619 features an active-low shutdown mode
that lowers the quiescent current to less than 300nA. In
shutdown mode, the inputs and output are high imped-
ance. This allows multiple devices to be multiplexed
onto a single line without the use of external buffers. Pull
SHDN high for normal operation.
amps ideal for signal processing applications. The
MAX9617, MAX9619, and MAX9620 are single-channel
devices. The MAX9618 is a dual-channel device. These
devices use an innovative autozero technique that allows
precision and low noise with a minimum amount of
power. The low input offset voltage, CMOS inputs, and
the absence of 1/f noise allows for optimization of active
filter designs.
The shutdown high (V ) and low (V ) threshold voltages
IH
IL
are designed for ease of integration with digital con-
trols like microcontroller outputs. These thresholds are
independent of supply, eliminating the need for external
pulldown circuitry.
The MAX9617–MAX9620 achieve rail-to-rail performance
at the input through the use of a low-noise charge pump.
This ensures a glitch-free, common-mode input voltage
range extending from the negative supply rail up to
the positive supply rail, eliminating crossover distortion
common to traditional n-channel/p-channel CMOS pair
inputs, reducing harmonic distortion at the output.
Applications Information
The MAX9617–MAX9620 low-power, low-noise, and
precision operational amplifiers are designed for appli-
cations in the portable medical, such as ECG and pulse
oximetry, portable consumer, and industrial markets.
The MAX9619 features a shutdown mode that greatly reduc-
es quiescent current when the device is not operational.
Autozero
The MAX9617–MAX9620 feature an autozero circuit that
allows the device to achieve less than 10FV (max) of
input offset voltage and eliminates the 1/f noise.
The MAX9617–MAX9620 are also ideal for loop-powered
systems that interface with pressure sensors or strain
gauges.
Capacitive-Load Stability
Driving large capacitive loads can cause instability in
many op amps. The MAX9617–MAX9620 are stable
with capacitive loads up to 400pF. Stability with higher
capacitive loads can be improved by adding an isolation
resistor in series with the op-amp output. This resistor
improves the circuit’s phase margin by isolating the load
capacitor from the amplifier’s output. The graph in the
Typical Operating Characteristics gives the stable oper-
ation region for capacitive load versus isolation resistors.
Internal Charge Pump
An internal charge pump provides an internal supply typi-
cally 1V beyond the upper rail. This internal rail allows the
MAX9617–MAX9620 to achieve true rail-to-rail inputs and
outputs, while providing excellent common-mode rejec-
tion, power-supply rejection ratios, and gain linearity.
The charge pump requires no external components, and
in most applications is entirely transparent to the user.
The operating frequency is well beyond the unity-gain

Single/Dual SC70, Zero-Drift,
High-Efficiency, 1.5MHz Op Amps with RRIO
Careful layout technique helps optimize performance by
decreasing the amount of stray capacitance at the op
amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
Power Supplies and Layout
The MAX9617–MAX9620 operate either with a single
supply from +1.6V to +5.5V with respect to ground or
with dual supplies from Q0.8V to Q2.75V. When used with
dual supplies, bypass both supplies with their own 0.1FF
capacitor to ground. When used with a single supply,
bypass VDD with a 0.1FF capacitor to ground.
