DESCRIPTION
The LTC
®
6244 is a dual high speed, unity-gain stable CMOS
op amp that features a 50MHz gain bandwidth, 40V/μs slew
rate, 1pA of input bias current, low input capacitance and
rail-to-rail output swing. The 0.1Hz to 10Hz noise is just
1.5μV
P-P
and 1kHz noise is guaranteed to be less than
12nV/√Hz. This excellent AC and noise performance is
combined with wide supply range operation, a maximum
offset voltage of just 100μV and drift of only 2.5μV/°C,
making it suitable for use in many fast signal processing
applications, such as photodiode amplifiers.
This op amp has an output stage that swings within 35mV
of either supply rail to maximize the signal dynamic range
in low supply applications. The input common mode
range extends to the negative supply. It is fully specified
on 3V and 5V, and an HV version guarantees operation
on supplies of ±5V.
The LTC6244 is available in the 8-pin MSOP and for com-
,
pact designs, it is packaged in the tiny dual fine pitch lead
free (DFN) package.
