Descripción general

Description

The ADC0808CCVX is an 8-channel, 8‑bit analog-to-digital converter with a multiplexer. It converts one of eight analog inputs (IN0–IN7) into a parallel 8‑bit digital word.
Key points:
- 8 input channels; 8‑bit resolution
- External clock on CLK (typical 4–6 MHz)
- Channel select via A, B, C inputs (selects 0–7)
- START input begins a conversion; EOC signals when complete
- Data outputs D0–D7 present the conversion result
- Reference range set by Vref+ and Vref− (commonly 0 to Vref)
- Single 5V supply operation (4.5–5.5V)
- CCVX suffix denotes a specific packaging variant of the ADC0808 family
Usage:
- Select channel with A–C, apply START
- Wait for EOC, read D0–D7
- Repeat for other channels or continuous scanning
Ideal for cost-effective microcontroller projects needing multiple analog inputs without a serial interface.

Features

ADC0808CCVX Features:
- 8-bit resolution with 8-channel input multiplexer (I0–I7)
- Successive-Approximation Register (SAR) ADC with on-chip sample-and-hold
- Single +5 V supply
- External clock input (CLK): typical 4–6 MHz (works over a broader range with clock frequency; conversion time clock-dependent)
- 8-bit parallel digital output (D0–D7), TTL/CMOS compatible
- Control pins: CS, RD, WR; Start input to begin conversion
- Channel select via 3 address lines (A0–A2)
- 28-pin package (DIP/SOIC) variant available (CCVX suffix)
- Input range 0 to Vref (commonly 0–5 V when Vref tied to VCC)
- Simple interface for microcontrollers; data valid after a read operation
Note: Conversion time depends on clock frequency; typical applications are fast enough for many MCU tasks.

Package

The ADC0808CCVX uses a 28-pin plastic DIP package (DIP-28).

Pinout

Pin count: 28 pins.
Function: 8-channel, 8-bit analog-to-digital converter with an internal multiplexer. It accepts eight analog inputs (IN0–IN7), converts the selected channel to an 8-bit digital output (D0–D7) using an external clock (CLK). Channel select is via 3 address lines (A0–A2). A start input (START) initiates a conversion; a data read interface (CS/RD/WR or OE) provides the result, with an End-of-Conversion (EOC) indicator signaling when data is ready. The CCVX suffix indicates a 28-pin package variant.

Manufacturer

Manufacturer: National Semiconductor Corporation (now part of Texas Instruments).
What kind of company: An American semiconductor company that designs and manufactures integrated circuits, especially analog and mixed-signal ICs (e.g., ADCs, op-amps, DACs).

Application

ADC0808CCVX is an 8-bit, 8-channel multiplexed SAR ADC with a 0–5 V input range. It interfaces to microcontrollers via a parallel data bus. Common applications: multi-sensor data acquisition and instrumentation (temperature, humidity, light, pressure, gas sensors, potentiometric signals), voltage/current monitoring, prototype automation/control systems, bench instrumentation, and educational lab experiments.
