ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The input offset voltage is measured with respect to AGND (Pin 1).
The input (Pin 4) is also shorted to the AGND pin. The analog ground pin
potential is internally set to (0.437)(V
SUPPLY
).
The l denotes the specifi cations which apply over the full operating
temperature range. f
CUTOFF
is the fi lter’s cutoff frequency and is equal to f
CLK
/50. The f
CLK
signal level is TTL or CMOS (clock rise or
fall time ≤ 1µs) R

A
= 25°C, unless otherwise specifi ed. All AC gains are measured relative to the passband gain.

Operating Supply Voltage (Note 3) 310V
Note 3: The input voltage can swing to either rail (V
+
or ground); the
output typically swings 50mV from ground and 0.8V from V
+
.
Note 4: The LTC1069-6 is optimized for 3V and 5V operation. Although
the device can operate with a single 10V supply or ±5V, the total harmonic
distortion will be degraded. For single 10V or ±5V supply operation we
recommend to use the LTC1069-1.
