MAX9614/MAX9616
Low-Power Single/Dual, Rail-to-Rail Op Amps
Detailed Description
The MAX9614/MAX9616 are low-power op amps ideal
for signal processing applications due to the devices’
high precision and CMOS inputs.
The MAX9614 also features a low-power shutdown mode
that greatly reduces quiescent current while the device
is not operational.
The MAX9614/MAX9616 self-calibrate on power-up to elim-
inate effects of temperature and power-supply variation.
RF Immunity
The MAX9614/MAX9616 feature robust internal EMI filters
that reduce the devices’ susceptibility to high-frequency
RF signals such as from wireless and mobile devices.
This, combined with excellent DC and AC specifications,
makes these devices ideal for a wide variety of portable
audio and sensitive signal-conditioning applications.
Applications Information
Power-Up Autotrim
The MAX9614/MAX9616 feature an automatic power-up
autotrim that self-calibrates the VOS of these devices
to less than 100FV of input offset voltage. The autotrim
sequence takes approximately 10ms to complete, and is
triggered by an internal power-on reset (POR) circuitry.
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.
Take care to ensure that the power supply settles within
0.4ms of power-up after it crosses a POR threshold of
0.5V to ensure that a stable power supply is present
when it steps through its autotrim sequence. If the power
supply glitches below the 0.5V threshold, the POR cir-
cuitry reactivates during next power-up.
Shutdown Operation
The MAX9614 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 operate by either a
1.8V or 3.3V microcontroller.
Interfacing with the MAX11613
The MAX9616 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.
The MAX9614/MAX9616’s 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 cur-
rent and capacitance drive capability of the part help
it to be useful in ADC driver and line-driver.
