Applications Information
Power-Up Autotrim
The MAX9613/MAX9615 feature an automatic autotrim
that self-calibrates the VOS of these devices to less than
100FV of input offset voltage (Figure 3). The autotrim
sequence takes approximately 3ms to complete, and is
triggered by an internal power-on reset (POR) threshold
of 0.5V. During this time, the inputs and outputs are put
into high impedance and left unconnected. This self-
calibration feature allows the device to eliminate input
offset voltage effects due to power supply and operating
temperature variation simply by cycling its power.
If the power supply glitches below the 0.5V threshold,
the POR circuitry reactivates during next power-up.
Shutdown Operation
The MAX9613 features an active-low shutdown mode
that puts both inputs and outputs into a high-impedance
state. In this mode, the quiescent current is less than
1FA. Putting the output in high impedance allows mul-
tiple signal outputs to be multiplexed onto a single output
line without the additional external buffers. The device
does not self-calibrate when exiting shutdown mode,
and retains its power-up trim settings. The device also
instantly recovers from shutdown.
The shutdown logic levels of the device are independent
of supply, allowing the shutdown to be operated by
either a 1.8V or 3.3V microcontroller.
Rail-to-Rail Input/Output
The input voltage range of the MAX9613/MAX9615
extends 100mV above VCC and below ground. The wide
input common-mode voltage range allows the op amp to
be used as a buffer and as a differential amplifier in a wide
variety of signal processing applications. Output voltage
low is designed to be especially close to ground—it is
only 11mV above ground, allowing maximum dynamic
range in single-supply applications. High output current
and capacitance drive capability of the part help it to be
useful in ADC driver and line driver applications.
Interfacing with the MAX11613
The MAX9615 dual amplifier’s low power and tiny size
is ideal for driving multichannel analog-to-digital con-
verters (ADCs) such as the MAX11613. See the Typical
Application Circuit. The MAX11613 is a low-power,
12-bit I2C ADC that measures either four single-ended
or two differential channels in an 8-pin FMAX pack-
age. Operating from a single 3V or 3.3V supply, the
MAX11613 draws a low 380FA supply current when sam-
pling at 10ksps. The MAX11613 family also offers pin-
compatible 5V ADCs (MAX11612) and 8-bit (MAX11601)
and 10-bit (MAX11607) options.
Input Bias Current
The MAX9613/MAX9615 feature a high-impedance
CMOS input stage and a specialized ESD structure
that allows low input bias current operation at low input
common-mode voltages. Low input bias current is
useful when interfacing with high-ohmic sensors. It is
also beneficial for designing transimpedance amplifiers
for photodiode sensors. This makes these MAX9613/
MAX9615 devices ideal for ground referenced medical
and industrial sensor applications.
Active Filters
The MAX9613/MAX9615 are ideal for a wide variety of
active filter circuits that make use of their rail-to-rail input/
output stages and high-impedance CMOS inputs. The
Typical Application Circuit shows an example Sallen-Key
active filter circuit with a corner frequency of 10kHz. At
low frequencies, the amplifier behaves like a simple low-
distortion noninverting buffer, while its high bandwidth
gives excellent stopband attenuation above its corner
frequency. See the Typical Application Circuit.
