Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CG variant meets commercial temperature requirements (0°C to 70°C). Ensure supply voltages are strictly maintained within the recommended operating conditions of VDD = 5V and VSS = -5V to guarantee specified performance parameters.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high accuracy with moderate speed and low power consumption. The internal reference eliminates external component count if a 2.5V reference is acceptable. For single-ended signals, ground AIN– to utilize the differential input structure effectively. Consider the 400ns acquisition time when driving high source impedance circuits without buffering.
