There are cost benefits in having a single operating supply. Single supply video systems can take advantage of the LMH6601’s low supply voltage operation along with its ability to operate with input common mode voltages at or slightly below the V− rail.

LMH6601, LMH6601-Q1 www.ti.com SNOSAK9E – JUNE 2006 – REVISED MARCH 2013 With the LMH6601 input bias current in the femto-amperes range, even large values of gain (RF) do not increase the output error term appreciably. This allows circuit operation to a lower light intensity level which is always of special importance in these applications.
