ADV7127 is a high performance video DAC chip produced by Analog Devices. It uses CMOS process and the maximum operating frequency can reach 240MHz. It supports 10-bit data input and the output SFDR can reach -70dB. The chip has RS-343A/RS-170 compatible output, complementary output, TTL compatible input and other characteristics, which can be applied to digital video systems, high resolution color graphics, digital radio and other fields.
The ADV7127 is a high‑speed 10‑bit video digital‑to‑analog converter fabricated in a CMOS process. It features a single‑supply operation (+5 V/+3.3 V), internal voltage reference (1.23 V) on the TSSOP package, TTL‑compatible inputs and complementary outputs.
The device is offered in 28‑lead SOIC and 24‑lead TSSOP packages and supports a throughput of 240 MSPS. It provides output currents from 2 mA to 26 mA, low power dissipation (30 mW @ 3 V) and operates over an industrial temperature range of –40 °C to +85 °C. Applications include digital video systems, high‑resolution graphics, DDS, and wireless LAN.
