Product details
Overview
ADC0820CCM+ from Maxim Integrated is an 8-bit, 10 MSPS analog-to-digital converter with CMOS technology, internal track-and-hold, and TTL/CMOS-compatible digital outputs. It operates from a single +5V supply and features 0.5 LSB integral nonlinearity, making it suitable for high-speed data acquisition in digital oscilloscopes and communication baseband processing.
For engineers reviewing the ADC0820CCM+ datasheet, ADC0820CCM+ pinout, ADC0820CCM+ application, or ADC0820CCM+ equivalent, key selection considerations include sampling rate, INL/DNL performance, power supply requirements, and interface compatibility with FPGA or microcontroller digital buses.
Technical Context
The ADC0820CCM+ employs a flash conversion architecture with a built-in sample-and-hold amplifier, enabling full-scale conversion at 10 million samples per second. Its differential analog input supports 0 V to VREF range with external reference voltage up to +5 V.
Digital output is parallel 8-bit, directly compatible with TTL and CMOS logic families. The device uses a single +5 V supply and draws 120 mW typical power, with conversion initiated by a rising-edge CLK signal and completed within 100 ns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9220ARZ | 12-bit resolution, 10 MSPS, requires ±5 V supplies and external reference buffer | Better dynamic range for medical imaging; higher power and layout complexity | Choose AD9220ARZ when SNR > 70 dB is required; ADC0820CCM+ remains optimal for cost-sensitive 8-bit systems |

FAQ
What is the maximum sampling rate supported by the ADC0820CCM+?
The ADC0820CCM+ supports a maximum sampling rate of 10 million samples per second (10 MSPS). This is achieved using its internal flash architecture and track-and-hold circuit, with conversion completing within 100 ns after each rising CLK edge. The ADC0820CCM+ maintains specified INL and DNL performance up to this rated speed under recommended operating conditions.
Does the ADC0820CCM+ require external reference voltage?
Yes, the ADC0820CCM+ requires an external reference voltage applied to the VREF pin to define its full-scale input range. The reference can be any stable DC source between 1 V and +5 V, and the analog input range becomes 0 V to VREF. No internal reference is provided, so the ADC0820CCM+ relies on external precision references for accuracy-critical applications.
Is the ADC0820CCM+ compatible with 3.3 V logic systems?
No, the ADC0820CCM+ is not directly compatible with 3.3 V logic systems. Its digital outputs are TTL/CMOS-compatible but specified for +5 V operation, with VOH ≥ 2.4 V and VOL ≤ 0.5 V under load. Interfacing with 3.3 V devices requires level-shifting circuitry; the ADC0820CCM+ itself must be powered from +5 V and does not support mixed-voltage I/O.
What package type is used for the ADC0820CCM+?
The ADC0820CCM+ is packaged in a 20-pin plastic dual in-line package (PDIP) with 0.3-inch width and through-hole mounting. This package matches industry-standard DIP-20 footprints and supports manual or wave soldering. The "CM" suffix in ADC0820CCM+ explicitly denotes this ceramic/metal hybrid DIP variant qualified for commercial temperature range (0°C to +70°C).
Can the ADC0820CCM+ operate with differential analog inputs?
Yes, the ADC0820CCM+ accepts differential analog inputs via ANALOG IN (+) and ANALOG IN (–) pins. It functions as a pseudo-differential ADC, rejecting common-mode noise when both inputs are driven with complementary signals referenced to the same VREF. However, the device does not include a fully differential input stage; the input range remains 0 V to VREF, centered on VREF/2 for differential use. This behavior is documented in the ADC0820CCM+ datasheet.
