The MAX1181 is a 3V, dual 10-bit, analog-to-digital converter (ADC) featuring fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine- stage ADCs. The MAX1181 is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital communication applications. The MAX1181 operates from a single 2.7V to 3.6V supply, consuming only 246mW, while delivering a typi- cal signal-to-noise ratio (SNR) of 59dB at an input fre- quency of 20MHz and a sampling rate of 80Msps. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1181 features a 2.8mA sleep mode, as well as a 1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of the internal or external reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1181 features parallel, CMOS-compatible three-state outputs. The digital output format is set to two’s complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfac- ing. The MAX1181 is available in a 7mm ✕ 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) te
The MAX1181 is a 3 V, dual 10‑bit analog‑to‑digital converter featuring fully‑differential wideband track‑and‑hold inputs and two pipelined nine‑stage ADCs. It operates from a single 2.7 V to 3.6 V supply and offers low‑power modes including a 2.8 mA sleep and 1 µA shutdown. Key features include an internal 2.048 V precision bandgap reference, selectable output format (two’s complement or offset binary), parallel CMOS three‑state outputs, and a 48‑pin TQFP‑EP package suitable for extended‑temperature industrial applications.
