LT1815/LT1816/LT1817
Single/Dual/Quad 220MHz,
1500V/s Operational Ampli ers
with Programmable Supply Current
FEATURES DESCRIPTION
n
220MHz Gain-Bandwidth Product
The LT 1815/LT1816/LT1817 are low power, high speed,
n
1500V/s Slew Rate
very high slew rate operational ampli ers with excellent
n
6.5mA Supply Current per Ampli er
DC performance. The LT1815/LT1816/LT1817 feature
n
Programmable Current Option
higher bandwidth and slew rate, much lower input offset
n
6nV/Hz Input Noise Voltage
voltage and lower noise and distortion than other devices
n
Unity-Gain Stable
with comparable supply current. A programmable current
n
1.5mV Maximum Input Offset Voltage
option (LT1815 and LT1816A) allows power savings and
n
8A Maximum Input Bias Current
exibility by operating at reduced supply current and speed.
n
800nA Maximum Input Offset Current
The circuit topology is a voltage feedback ampli er with the
n
50mA Minimum Output Current, V = 3V
slewing characteristics of a current feedback ampli er.
OUT
n
3.5V Minimum Input CMR, V = 5V
S
The output drives a 100 load to 3.8V with 5V supplies.
n
Speci ed at 5V, Single 5V Supplies
On a single 5V supply, the output swings from 1V to 4V
n
Operating Temperature Range: 40C to 85C
with a 100 load connected to 2.5V. Harmonic distortion
n
Space Saving MSOP and SSOP Packages
is 70dB for a 5MHz, 2V output driving a 100 load
P-P
n
Low Pro le (1mm) SOT-23 (ThinSOT) and Leadless
in a gain of 1.
DFN Packages
The LT1815/LT1816/LT1817 are manufactured on Linear
