DESCRIPTIONThe OPA2683 provides a new level of performance for dual, very
low-power, wideband, current-feedback amplifiers. This CFBPLUS
amplifier is among the first to use an internally closed-loop input
buffer stage that significantly enhances performance over earlier
low-power, current-feedback (CFB) amplifiers. This new archi-
tecture provides many of the advantages of a more ideal CFB
amplifier while retaining the benefits of very low-power operation.
The closed-loop input stage buffer gives a very low and linearized
impedance path at the inverting input to sense the feedback error
current. This improved inverting input impedance gives excep-
tional bandwidth retention to much higher gains and improved
harmonic distortion over earlier solutions limited by inverting input
linearity. Beyond simple high gain applications, the OPA2683
CFBPLUS amplifier can allow the gain setting element to be set with
considerable freedom from amplifier bandwidth interaction. This

SHORT-LOOP ADSL CO DRIVERS MULTICHANNEL SUMMING AMPLIFIERS PROFESSIONAL CAMERAS DIFFERENTIAL ADC INPUT DRIVERSflexibility allows frequency response peaking elements to be
added, multiple input inverting summing circuits to have greater
bandwidth, and low-power differential line drivers to meet the
demanding requirements of DSL.
The output capability for the OPA2683 also sets a new mark in
performance for very low-power, current-feedback amplifiers. De-
livering a full ±4VPP swing on ±5V supplies, the OPA2683 also has
the output current to support this swing into a 100Ω load. This
minimal output headroom requirement is complemented by a
similar 1.2V input stage headroom, giving exceptional capability for
single +5V operation.
The OPA2683’s low 1.9mA total supply current is precisely trimmed
at +25°C. This trim, along with low shift over temperature and supply
voltage, gives a very robust design over a wide range of operating
conditions. Further system power reduction is possible using
the shutdown feature of the MSOP-10 package.
