PRELIMINARY
Micropower Single Supply Rail-to-Rail
Input-Output Precision Op Amp
Features
• 50µA supply current
The EL8178 is a micropower precision operational amplifier
optimized for single supply operation at 5V and can operate
down to 2.4V.
• 100µV max offset voltage
• 1pA input bias current
• 400kHz gain-bandwidth product
• 0.13V/µs slew rate
The EL8178 draws minimal supply current while meeting
excellent DC-accuracy noise and output drive specifications.
Competing devices seriously degrade these parameters to
achieve micropower supply current. Offset current, voltage
and current noise, slew rate, and gain-bandwidth product are
all two to ten times better than on previous micropower op
amps.
• Single supply operation down to 2.4V
• Rail-to-rail input and output
• Output sources and sinks 26mA load current
Applications
The 1/f corner of the voltage noise spectrum is at 1kHz. This
results in low frequency noise performance which can only
be found on devices with an order of magnitude higher
supply current.
• Battery- or solar-powered systems
• 4mA to 25mA current loops
• Handheld consumer products
• Medical devices
The EL8178 can be operated from one lithium cell or two
Ni-Cd batteries. The input range includes both positive and
negative rail. The output swings to both rails.
• Thermocouple amplifiers
• Photodiode pre amps
• pH probe amplifiers
