CBM8538-CBM8539
OPERATION INSTRUCTION
Features
Description
Low Offset Voltage: 1uV
The CBM8538, CBM8539 series of CMOS
operational amplifiers use auto-zero
Input Offset Drift: 0.005μV/°C
High Gain Bandwidth Product: 1.6MHz
Rail-to-Rail Input and Output
techniques to simultan-eously provide very
low offset voltage (5μV max) and near-zero
drift over time and temperature. This family of
amplifiers has ultralow noise, offset and
power.
High Gain, CMRR, PSRR:130dB
High Slew Rate: 0.7V/μs
Low Noise: 1.3uVp-p (0.01~10Hz)
Low Power Consumption: 180μA /op amp
Overload Recovery Time:2us
This miniature, high-precision operational
amplifiers offer high input impedance and
rail-to-rail input and rail-to-rail output swing.
With high gain-bandwidth product of 1.6MHz
and slew rate of 0.7V/μs.
Low Supply Voltage: +2.5 V to +5.5 V
No External Capacitors Required
Extended Temperature: -40°C to +125°C
Single or dual supplies as low as
+2.5V(±1.25V) and up to +5.5V (±2.75V) may
be used.
