Precision C-Load Op Amps
DESCRIPTION
The LT
output precision C-Load
bandwidth product and a 6V/ s slew rate.
The LT1498/LT1499 are designed to maximize input
dynamic range by delivering precision performance over
the full supply voltage. Using a patented technique, both
input stages of the LT1498/LT1499 are trimmed, one at the
negative supply and the other at the positive supply. The
resulting guaranteed common mode rejection is much
better than other rail-to-rail input op amps. When used as a
unity-gain buffer in front of single supply 12-bit A-to-D
converters, the LT1498/LT1499 are guaranteed to add less
than 1LSB of error even in single 3V supply systems.
With 110dB of supply rejection, the LT1498/LT1499 main-
tain their performance over a supply range of 2.2V to 36V
and are specified for 3V, 5V and 15V supplies. The inputs
can be driven beyond the supplies without damage or
phase reversal of the output. These op amps remain stable
while driving capacitive loads up to 10,000pF.
The LT1498 is available with the standard dual op amp
configuration in 8-pin PDIP and SO packaging. The LT1499
features the standard quad op amp configuration and is
available in a 14-pin plastic SO package. These devices can
be used as plug-in replacements for many standard op
amps to improve input/output range and precision.

... U APPLICATIONS INFORMATION Rail-to-Rail Input and Output The LT1498/LT1499 are fully functional for an input and output signal range from the negative supply to the posi- tive supply. Figure 1 shows a simplified schematic of the amplifier. The input stage consists of two differential amplifiers, a PNP stage (Q1/Q2) and an NPN stage (Q3/ Q4) which are active over different ranges of input com- mon mode voltage ...

Page 12

... Worst-case differential input voltage usually occurs when the output is shorted to ground. In addition, the amplifier is protected against ESD strikes up to 3kV on all pins. Capacitive Load The LT1498/LT1499 are designed for ease of use. The amplifier can drive a capacitive load of more than 10nF ...
