The MAX3275/MAX3277 transimpedance amplifiers
provide a compact low-power solution for communica-
tion up to 2.125Gbps. They feature 300nA input-
referred noise at 2.1GHz bandwidth (BW) with 0.85pF
input capacitance. The parts also have 2mA
input overload.
The MAX3277 is identical to the MAX3275, but with the
output polarities inverted for optimum packaging flexi-
bility. Both parts operate from a single 3.3V supply and
consume only 83mW. The MAX3275/MAX3277 are
compact 24mil x 47mil die and require no external com-
pensation capacitor. A space-saving filter connection is
provided for positive bias to the photodiode through an
on-chip 600Ω resistor to V
easy assembly into a TO-46 or TO-56 header with a
photodiode.
The MAX3275/MAX3277 and MAX3274 limiting ampli-
fiers provide a two-chip solution for dual-rate, fibre
channel receiver applications.
