The ADV7401 is a 10-bit, integrated, multiformat SDTV/HDTV video decoder and RGB graphics digitizer. It features four 10-bit ADCs with sampling rates up to 140 MHz, a 12-channel analog input multiplexer, SCART fast blank support, internal anti-aliasing filters, NTSC/PAL/SECAM color standard support, 525p-/625p-component progressive scan support, 720p-/1080i-component HDTV support, a 24-bit digital input port that supports data from DVI/HDMI Rx ICs, an any-to-any, 3×3 color-space conversion matrix, an industrial temperature range of (-40°C to +85°C), a 12-bit 4:4:4/8-bit 4:2:2 DDR pixel output interface, a programmable interrupt request output pin, and a VBI data slicer (including teletext).
The ADV7401 is a single‑chip, multiformat video decoder and graphics digitizer that supports PAL, NTSC, SECAM, and various component video standards. It converts analog video signals to digital ITU‑R BT.656 format and can digitize RGB graphics up to SXGA resolution.

| ADC resolution | 10 bits |
|---|---|
| Operating temperature range | -40 °C to +85 °C |
| Core supply voltage (AVDD) | 3.15 V to 3.45 V |
| Digital I/O supply voltage (DVDDIO) | 3.0 V to 3.6 V |
| Package type | 100‑Lead Low Profile Quad Flat Package (LQFP) |
The device operates from –40 °C up to +85 °C.
AVDD is 3.15 V–3.45 V, DVDD is 1.65 V–2.0 V, DVDDIO is 3.0 V–3.6 V, and PVDD is 1.71 V–1.89 V.
Each of the four ADCs provides a 10‑bit resolution.
