Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging as per the manufacturer's ordering information. Confirm the 'ACG' designation corresponds to the commercial temperature range (0°C to 70°C) and SSOP-28 package. Cross-reference the datasheet revision to ensure compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1605ACG#PBF for applications requiring 16-bit accuracy at moderate speeds with low power consumption. The 'A' grade ensures tighter linearity specifications (±2.0 LSB INL) compared to standard grades. Ensure the system can accommodate the parallel interface timing requirements and that the ±10V input range matches the sensor signals without external attenuation.
