LT1567

OAOUT (Pin 1):
Output of the Uncommitted Op Amp (OA).
As with most wideband op amps, it is important to avoid
connecting heavy capacitive loads (above about 10pF)
directly to this output. Such loads, exhibiting low imped-
ance (circa 100
) at the op amp’s unity-gain crossover
frequency (circa 100MHz), will impair AC stability.
OAIN (Pin 2):
Inverting or “–” Input of the Uncommitted
Op Amp (OA) in the LT1567. The noninverting or “+” input
of this amplifier is shared with that of the INV amplifier and
accessed via the GND and BYPASS pins. The OA amplifier
is optimized for minimal wideband noise.
BYPASS (Pin 3):
AC Ground Bypass. Designed for a
decoupling capacitor, typically 0.1
μ
F, to a printed circuit
ground plane using the shortest possible wiring. Use GND
for DC connection of the amplifier noninverting inputs as
described in the GND (Pin 5) description.
Power Supply Pins (Pins 4, 8):
The V
–
and V
+
pins should
be bypassed with 0.1
μ
F capacitors to an adequate analog
ground plane using the shortest possible wiring. Electri-
cally clean supplies and a low impedance ground are
important for the high dynamic range and bandwidth
available from the LT1567. Low noise linear power sup-
plies are recommended. Switching supplies are not rec-
ommended because of the inevitable risk of their switch-
ing noise coupling into the signal path, reducing dynamic
range.
PIU
GND (Pin 5):
DC Ground Input. Sets the noninverting
inputs for the two internal amplifiers; designed for use as
a DC reference, not a signal input.The GND input includes
a small series resistor, both to balance DC offsets in the
presence of input bias currents and also to suppress the
“Q” factor of possible parasitic high-frequency resonant
circuits introduced by wiring inductance. The on-chip
ground reference at the noninverting inputs of the two
amplifiers is decoupled for very high frequencies with a
small internal capacitor to the chip substrate, nominally
7pF. An external capacitor, typically 0.1
μ
F, to a nearby
ground plane should be added at the BYPASS pin for a
clean wideband ground reference.
INVIN (Pin 6):
Unity-Gain Inverter Input. The “inverter”
(INV) amplifier in the LT1567 is connected to internal
resistors (nominally 600
each) to form a closed-loop
amplifier with a wideband voltage gain of nominally –1.
The amplifier in this position is similar to the uncommitted
op amp (OA) but is optimized for high frequency linearity.
INVOUT (Pin 7):
Output of the INV or “Inverter” Amplifier,
with a Nominal Gain of –1 from the INVIN Pin. As with
most wideband op amps, it is important to avoid connect-
ing heavy capacitive loads (above about 10pF) directly to
this output. Such loads, exhibiting low impedance (circa
100 ohms) at the op amp’s unity-gain crossover frequency
(circa 100MHz), will impair AC stability.
