For help about Application of ICL7135

[466576266]

hello,anyone. recently, i am developing a project about the ICL7135,. but i meet with a problem. I intend to
choose the intersil's product ICL7135. when i am planning to begin the project, i dont know how to option
the peripherial component diode, see the attached picture marked with read word.
could you give me some options about the component? thanks in advance.

Why not just read the datasheet?

Rollover Resistor and Diode
A small rollover error occurs in the ICL7135, but this can be
easily corrected by adding a diode and resistor in series
between the INTegrator OUTput and analog COMMON or
ground. The value shown in the schematics is optimum for
the recommended conditions, but if integrator swing or clock
frequency is modified, adjustment may be needed. The
diode can be any silicon diode such as 1N914. These
components can be eliminated if rollover error is not
important and may be altered in value to correct other
(small) sources of rollover as needed.

hey, Nigel Goodwin. thanks for your help. i feel that i am really careless about the datasheet. i didnt research the ending part of the datasheet. really thanks.
