DICE SPECIFICATION
LTC1093

LT 1205 PRINTED IN USA
LINEAR TECHNOLOGY CORPORATION 2005
Wafer level testing is performed per the indicated specifications for dice. Considerable differences in performance can often be observed for dice versus
packaged units due to the influences of packaging and assembly on certain devices and/or parameters. Please consult factory for more information on
dice performance and lot qualifications via lot sampling test procedures.
Dice data sheet subject to change. Please consult factory for current revision in production.

(Notes 1, 2)
Note 1: All voltage values are with respect to ground with DGND, AGND,
GND and REF– wired together (unless otherwise noted).
Note 2: VCC = 5V, VREF = 5V, V– = 0V for unipolar mode and –5V for
bipolar mode, CLK = 0.5MHz unless otherwise specified.
Note 3: These specs apply for both unipolar and bipolar modes. In bipolar
mode, one LSB is equal to the bipolar input span (2VREF) divided by 1024.
For example, when VREF = 5V, 1LSB (bipolar) = 2(5V)/1024 = 9.77mV.
Note 4: Linearity error is specified between the actual end points of the
A/D transfer curve.
Note 5: Total unadjusted error includes offset, full scale, linearity,
multiplexer and hold step errors.
Note 6: Two on-chip diodes are tied to each reference and analog input
which will conduct for reference or analog input voltages one diode drop
below V– or one diode drop above VCC. Be careful during testing at low
VCC levels (4.5V), as high level reference or analog inputs (5V) can cause
this input diode to conduct, especially at elevated temperatures, and cause
errors for inputs near full scale. The spec allows 50mV forward bias of
either diode. This means that as long as the reference or analog input does
not exceed the supply voltage by more than 50mV, the output code will be
correct. To achieve an absolute 0V to 5V input voltage range will therefore
require a minimum supply voltage of 4.950V over intial tolerance,
temperature variations and loading.
Note 7: Channel leakage current is measured after the channel selection.
