Key Parameters

Substitute Part Grouping Explanation

Substitution for ADC0808CCN is determined strictly through the following key electrical and mechanical parameters: bit width (8 bits), input count (8 channels), input type (single ended), converter architecture (SAR), configuration (MUX-S/H-ADC: 1:1), number of ADCs (1), and compatible supply voltage ranges. Data interface compatibility and package type are also considered. Only parts matching or exceeding these specified requirements are included. Environmental compliance status and product availability are relevant for selection but not substitutability.

Parameter Comparison

Engineering Selection Recommendations

ADC0808CCN is listed as obsolete and RoHS non-compliant. The substitute, ADC088S022CIMT/NOPB, is active and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Both products are REACH unaffected and share EAR99 ECCN status. Selection should be based on current product status to ensure supply continuity and adherence to relevant environmental directives according to application requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when substituting ADC0808CCN?
Substitution is determined by matching bit width, input count, input type, converter configuration, architecture, number of ADCs, and compatible supply voltage ranges. Package and mounting type differences must be considered for mechanical compatibility.

Q2: Are there interface differences between ADC0808CCN and its substitute?
ADC0808CCN features a parallel data interface, whereas ADC088S022CIMT/NOPB offers SPI and DSP interfaces. System design modifications may be required to accommodate interface changes.

Q3: Is the substitute’s package compatible with the original?
ADC0808CCN is in a 28-DIP through-hole package; ADC088S022CIMT/NOPB is in a 16-TSSOP surface mount package. Mechanical compatibility must be confirmed based on board layout and assembly process.

Q4: Does the substitute meet current environmental standards?
ADC088S022CIMT/NOPB is ROHS3 compliant and REACH unaffected. ADC0808CCN is RoHS non-compliant but REACH unaffected.

Q5: Are there supply voltage considerations when substituting?
ADC0808CCN operates with analog and digital supply voltages of 4.5V to 6.5V. ADC088S022CIMT/NOPB operates from 2.7V to 5.25V. Voltage levels must be compatible with the intended design.

Q6: What advantages does the substitute offer regarding temperature range?
ADC088S022CIMT/NOPB supports a wider operating temperature range (-40°C to 105°C) compared to the original part (-40°C to 85°C).
