1. General Information & Absolute Maximum Ratings:

️· Device: LTC1606 (A/D Converter)
️· Absolute Maximum Ratings: These are values that, if exceeded, could damage the device. (Not really spec'd out here but important to note)
️· Voltage References: All voltages are relative to ground (DGND, AGND1, and AGND2 are tied together). Internal clamping diodes protect against voltages below ground and above VDD.

2. Electrical Characteristics (Typical Conditions):

️· Supply Voltage (VDD): 4.75 to 5.25 Volts
️· Supply Current (IDD): 15-20 mA
️· Power Dissipation: 75-100 mW
️· Sampling Frequency (fSAMPLE Max): 250 kHz

3. A/D Conversion Performance (Key Specs):

️· Integral Nonlinearity: This is a measure of how much the actual output code deviates from a perfect linear progression. (Not a specific value listed here, but it's a key characteristic)
️· Offset Error: A measure of the unwanted shift in the output. (Not a specific value listed here, but important).
️· Full-Scale Error: The maximum error at either the smallest or largest output codes. (Not a specific value listed here, but important).
️· Conversion Time (tCONV): 2.5 µs
️· Acquisition Time (tACQ): 1.5 µs

4. Timing Characteristics (Important for Interfacing):

️· t1 (Convert Pulse Width): 40 ns
️· t2 (Data Valid Delay): 2.5 µs
️· t3 (BUSY Delay): 65 ns
️· t4 (BUSY Low): 2.5 µs
️· t5 (BUSY Delay after Conversion): 100 ns
️· t7 (Bus Relinquish Time): 15-50 ns
️· t8 (BUSY Delay after Data Valid): 20-90 ns
️· t10 (R/C to CS Setup Time): 5 ns
️· t11 (Time Between Conversions): 4 µs
️· t12 (Byte Delay): 15-60 ns (Dependent on load capacitance)

5. Other Important Notes and Definitions:

️· BUSY Signal: This signal indicates when the converter is busy processing data.
️· R/C Timing: The converter is triggered by a falling edge of an RC circuit. There are specific timing requirements for the RC circuit.
️· Full-Power Bandwidth: A measure of the highest frequency signal that can be accurately converted.
️· Overvoltage Recovery: The converter can recover from an input overvoltage condition.
️· Notes: The datasheet contains a lot of notes explaining how certain specs are measured or what conditions apply. They are very important for interpreting the specifications.



In essence, this datasheet excerpt provides the fundamental electrical characteristics, timing information, and crucial notes needed to use the LTC1606 A/D converter effectively in a digital system.
