High-Density Systems
For battery-powered, portable applications where
power is of key importance, the low-power
consumption and high-frequency performance of the
OPA836 and OPA2836 devices offer performanceversus-power capability that is not attainable in other
devices. Coupled with a power-savings mode to
reduce current to < 1.5 μA, these devices offer an
attractive solution for high-frequency amplifiers in
battery-powered applications.
The OPA836 RUN package option includes
integrated gain-setting resistors for the smallest
possible footprint on a printed-circuit board
(approximately 2.00 mm × 2.00 mm). By adding
circuit traces on the PCB, gains of +1, –1, –1.33, +2,
+2.33, –3, +4, –4, +5, –5.33, +6.33, –7, +8 and
inverting attenuations of –0.1429, –0.1875, –0.25,
–0.33, –0.75 can be achieved. See Table 3 and
Table 4 for details.
The
OPA836
and
OPA2836
devices
are
characterized for operation over the extended
industrial temperature range of –40°C to +125°C.

F
Harmonic Distortion - dBc
The OPA836 and OPA2836 devices (OPAx836) are
single- and dual-channel, ultra-low power, rail-to-rail
output, negative-rail input, voltage-feedback (VFB)
operational amplifiers designed to operate over a
power-supply range of 2.5 V to 5.5 V with a single
supply, or ±1.25 V to ±2.75 V with a dual supply.
Consuming only 1 mA per channel and a unity-gain
bandwidth of 205 MHz, these amplifiers set an
industry-leading power-to-performance ratio for railto-rail amplifiers.
