The ICs feature a high-impedance CMOS input stage
and a specialized ESD structure that allows low-input
bias current operation at low-input, common-mode volt-
ages. Low-input bias current is useful when interfacing
with high-ohmic sensors. It is also beneficial for design-
ing transimpedance amplifiers for photodiode sensors.
This makes these devices ideal for ground-referenced
medical and industrial sensor applications.
The MAX44260/MAX44261 are ideal for a wide variety
of active filter circuits that make use of their wide band-
width, rail-to-rail input/output stages and high-impedance
CMOS inputs. The
example Sallen-Key active filter circuit with a corner
frequency of 10kHz. At low frequencies, the amplifier
behaves like a simple low-distortion noninverting buf-
fer, while its high bandwidth gives excellent stopband
attenuation above its corner frequency. See the

The ICs’ tiny size and low noise makes them a good fit for
driving 12- to 16-bit resolution ADCs in space-constrained
applications. The
MAX44260 amplifier output connected to a lowpass filter
driving the MAX11645 ADC. The MAX11645 is part of a
family of 3V and 5V, 12-bit and 10-bit, 2-channel ADCs.
The MAX11645 offers sample rates up to 94ksps and
measures two single-ended inputs or one differential
input. These ADCs dissipate 670FA at the maximum
sampling rate, but just 6FA at 1ksps and 0.5FA in shut-
down. Offered in the ultra-tiny, 1.9mm x 2.2mm WLP and
FMAX-8 packages, the MAX11645 ADCs are an ideal fit
to pair with the MAX44260/MAX44261 amplifiers in por-
table applications.
Where higher resolution is required, refer to the MAX1069
(14-bit) and MAX1169 (16-bit) ADC families.
