FN6337.2
4.5MHz, Single Dual and Quad Precision
Rail-to-Rail Input-Output (RRIO) Op Amps
www.wdatiatshheVete4ur.ycomLow Input Bias Current
The ISL28148, ISL28248 and ISL28448 are 4.5MHz
low-power single, dual and quad operational amplifiers. The
parts are optimized for single supply operation from 2.4V to
5.5V, allowing operation from one lithium cell or two Ni-Cd
batteries.
The single, dual and quad feature an Input Range
Enhancement Circuit (IREC) which enables them to maintain
CMRR performance for input voltages greater than the
positive supply. The input signal is capable of swinging
0.25V above the positive supply and to 100mV below the
negative supply with only a slight degradation of the CMRR
performance. The output operation is rail-to-rail.
The parts draw minimal supply current (900µA per amplifier)
while meeting excellent DC accuracy, AC performance,
noise and output drive specifications. The ISL28148 features
an enable pin that can be used to turn the device off and
reduce the supply current to a maximum of 16µA. Operation
is guaranteed over -40°C to +125°C temperature range.
Features
• 4.5MHz gain bandwidth product
• 900µA supply current (per amplifier)
• 1.8mV maximum offset voltage
• 1pA typical input bias current
• Down to 2.4V single supply operation
• Rail-to-rail input and output
• Enable pin (ISL28148 SOT-23 package only)
• -40°C to +125°C operation
• Pb-free (RoHS compliant)
Applications
• Low-end audio
• 4mA to 20mA current loops
• Medical devices
• Sensor amplifiers
• ADC buffers
• DAC output amplifiers

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
3. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
