ADC0804LCWMX

ADC0804LCWMX is an 8‑bit, single‑channel, successive‑approximation ADC (the ADC0804 family) used to digitize an analog signal for microcontrollers.
Key points:
- Resolution and range: 8-bit output; input typically 0 to Vref (often 0–5V if Vref is tied to Vcc).
- Clock and interface: Requires an external clock on CLK. Uses a simple, microcontroller–friendly parallel interface with CS, WR, RD, an 8‑bit data bus (D0–D7), and INTR (interrupt/ready) signaling conversion completion.
- Operation: Apply the analog signal to Vin; assert CS and generate a WR pulse to start a conversion; wait for INTR to indicate completion, then read the 8-bit result on D0–D7 during a RD cycle.
- Power/pin: Typically powered from 5V; reference voltage sets full-scale range.
- Packaging/code: LCWMX is a vendor/packaging suffix; check the exact datasheet for package type and pinout.
Common use: simple analog-to-digital conversion in microcontroller projects and educational experiments. For exact timing, pinout, and packaging, consult the ADC0804LCWMX datasheet.

Here are the common features of the ADC0804LCWMX:
- 8-bit successive-approximation analog-to-digital converter
- Single-ended input with 0–5V (Vref) range (typical 5V supply)
- External clock input: 4 to 6 MHz (CLK)
- Parallel 8-bit data output: D0–D7
- Microprocessor-compatible interface: CS, WR, RD
- Start of conversion via WR; read data via RD
- End-of-conversion indicator: INTR (interrupt) output
- One-channel A/D with internal track-and-hold characteristics
- Conversion time on the order of ~100 μs at typical clock (≈10 kSPS)
- Supply voltage commonly ≈5V (4.5–5.5V range in many variants)
Note: The LCWMX suffix denotes a specific package/lot variant of the device.

ADC0804LCWMX comes in an 18-pin plastic DIP (PDIP) package.

- Pin count: 18 pins (DIP/SOIC 18)
- Function: 8‑bit ADC with 8-channel multiplexed analog input. Requires an external clock. Converts selected analog input (CH0–CH7, chosen by A0–A2) to an 8‑bit digital word on D0–D7. Interface is parallel with control lines CS, RD, WR; INTR signals conversion complete.

Manufacturer: Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs. The ADC0804 was originally developed by National Semiconductor; TI acquired National Semiconductor in 2011 and continues to market/support the part.
