DESCRIPTIO

The LTC

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

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 ampliﬁ ers.

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 speciﬁ ed

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 ﬁ ne pitch lead

free (DFN) package.
