GENERAL DESCRIPTION
The SGM8606 is a high-precision and low power CMOS
operational amplifier that provides very low offset
voltage and zero-drift over time and temperature. One
comparator and one low drift voltage reference are
integrated with the amplifier.
The miniature, high-precision, low quiescent current
amplifier offers high-impedance inputs that have a wide
input common mode range of 100mV beyond the rails
and rail-to-rail output that swings within 14mV of the
rails. Single or dual supplies as low as 1.8V (±0.9V)
and up to 5.5V (±2.75V) may be used. It is optimized for
low voltage, single-supply operation.
The amplifier offers excellent CMRR without the
crossover associated with traditional complementary
input stages. This design results in superior performance
for driving analog-to-digital converters (ADCs) without
degradation of differential linearity.
The comparator’s input common mode range can be
200mV beyond the supply rails and the integrated
voltage reference provides precise threshold in
application.
The integrated 1.2V series voltage reference offers a
low 42µV/℃ drift. It is stable with up to 10nF capacitive
load, and can source up to 2mA (TYP) of output
current.
Designed to operate over a wide range of supply
voltages, from 1.8V to 5.5V, with guaranteed operation
at 1.8V and 5.0V, the SGM8606 is ideal for use in a
variety of battery-powered applications. With rail-to-rail
input common mode voltage range, the SGM8606 is
well suited for single-supply operation. Its small
package and low power make this device ideal for use
in handheld electronics and mobile phone applications.
The SGM8606 is available in a Green TDFN-3×3-10L
package. It is rated over the -40℃ to +85℃ temperature
range.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure
to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section
is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure
to observe proper handling
and installation procedures
can cause damage. ESD damage can range from subtle
performance
degradation to
complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
