Fast Settling Op Amp
PRODUCT DESCRIPTIONThe AD843 is a fast settling, 34 MHz, CBFET input op amp.
The AD843 combines the low (0.6 nA) input bias currents
characteristic of a FET input amplifier while still providing a
34 MHz bandwidth and a 135 ns settling time (to within 0.01%
of final value for a 10 volt step).The AD843 is a member of the
Analog Devices’ family of wide bandwidth operational amplifi-
ers. These devices are fabricated using Analog Devices’ junction
isolated complementary bipolar (CB) process. This process per-
mits a combination of dc precision and wideband ac perform-
ance previously unobtainable in a monolithic op amp.
The 250 V/μs slew rate and 0.6 nA input bias current of the
AD843 ensure excellent performance in high speed sample-and-
hold applications and in high speed integrators. This amplifier is
also ideally suited for high bandwidth active filters and high fre-
quency signal conditioning circuits.
Unlike many high frequency amplifiers, the AD843 requires no
external compensation and it remains stable over its full operat-
ing temperature range. It is available in five performance grades:
the AD843J and AD843K are rated over the commercial
temperature range of 0°C to +70°C. The AD843A and AD843B
are rated over the industrial temperature range of –40°C to +85°C.
The AD843S is rated over the military temperature range of –55°C
to +125°C and is available processed to MIL-STD-883B, Rev. C.

PRODUCT HIGHLIGHTSThe high slew rate, fast settling time and low input bias cur-
rent of the AD843 make it the ideal amplifier for 12-bit D/A
and A/D buffers, for high speed sample-and-hold amplifiers
and for high speed integrator circuits. The AD843 can re-
place many FET input hybrid amplifiers such as the
LH0032, LH4104 and OPA600.Fully differential inputs provide outstanding performance in
all standard high frequency op amp applications such as sig-
nal conditioning and active filters.Laser wafer trimming reduces the input offset voltage tomV max (AD843K and AD843B).Although external offset nulling is unnecessary in many ap-
plications, offset null pins are provided.The AD843 does not require external compensation at
closed loop gains of 1 or greater.
