Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltage values are with respect to ground with DGND, AGND1
and AGND2 wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below ground or above V
V
handle input currents of greater than 100mA below ground or above V
without latch-up.
Note 4: When these pin voltages are taken below ground, they will be
clamped by internal diodes. This product can handle input currents of
90mA below ground without latchup. These pins are not clamped to V
Note 5: V
specified.
Note 6: Linearity, offset and full-scale specifications apply for a V
with respect to ground.
Note 7: Integral nonlinearity is defined as the deviation of a code from a
straight line passing through the actual end points of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 8: Zero error for the LTC1605-1 is the voltage measured from
0.5LSB when the output code flickers between 0000 0000 0000 0000
and 0000 0000 0000 0001. Zero error for the LTC1605-2 is the voltage
measured from – 0.5LSB when the output code flickers between 0000
0000 0000 0000 and 1111 1111 1111 1111.

Note 9: Guaranteed by design, not subject to test.
Note 10: Recommended operating conditions.
Note 11: With CS low the falling R/C edge starts a conversion. If R/C
returns high at a critical point during the conversion it can create small
errors. For best results ensure that R/C returns high within 3 s after the
start of the conversion.
Note 12: As measured with fixed resistors shown in Figure 4. Adjustable to
zero with external potentiometer.
Note 13: Full-scale error is the untrimmed deviation from ideal last code
transition, divided by the full-scale range and includes the effect of offset
error.
Note 14: All specifications in dB are referred to a full-scale 4V input for the
LTC1605-1 and to 4V input for the LTC1605-2.
Note 15: Full-power bandwidth is defined as full-scale input frequency at
which a signal-to-(noise + distortion) degrades to 60dB or 10 bits of
accuracy.
Note 16: Recovers to specified performance after ( 20V) input
overvoltage for the LTC1605-1 and 15V for the LTC1605-2.
