The ADC1173 is a low power, 15 MSPS analog-to-digital converter that digitizes signals to 8 bits while consuming just 33 mW of power (typ). The ADC1173 uses a unique architecture that achieves 7.6 Effective Bits. Output formatting is straight binary coding. The excellent DC and AC characteristics of this device, together with its low power consumption and +3V single supply operation, make it ideally suited for many video, imaging and communications applications, including use in portable equipment. Furthermore, the ADC1173 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC1173’s reference ladder is available for connections, enabling a wide range of input possibilities.
The ADC1173 is an 8‑bit, 15 MSPS analog‑to‑digital converter that operates from a single +3 V supply and consumes only 33 mW typical power. It features an internal sample‑and‑hold function, tri‑state outputs, and a reference ladder that provides 7.6 effective bits of resolution.
The device is offered in SOIC and TSSOP packages and is suited for video digitization, digital cameras, set‑top boxes, and other portable equipment. Detailed pin descriptions, electrical characteristics, and mechanical dimensions are provided for designers.
