RH1028M/RH1128M
Ultralow Noise Precision
High Speed Op Amps
Description Absolute Maximum Ratings The RH1028(gain of –1 stable)/RH1128(gain of +1 stable)
achieve a new standard of excellence in noise performance
with 0.9nV/√Hz 1kHz noise, 1.0nV/√Hz 10Hz noise. This
ultralow noise is combined with excellent high speed specifications (gain-bandwidth product is 75MHz for RH1028,
20MHz for RH1128), distortion-free output, and true precision parameters (0.25µV/°C drift, 20µV offset voltage, 25
million voltage gain). Although the RH1028/RH1128 input
stage operates at nearly 1mA of collector current to achieve
low voltage noise, input bias current is only 50nA. Supply Voltage (–55°C to 125°C).±16V
Differential Input Current (Note 9).±25mA
Input Voltage.Equal to Supply Voltage

of a 50Ω resistor. Therefore, even in very low source
impedance transducer or audio amplifier applications,
the RH1028/RH1128’s contribution to total system noise
will be negligible. burn-in circuit PACKAGE INFORMATION
