The MAX1180 is a 3.3V, 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 MAX1180 is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital communication applications. The MAX1180 operates from a single 2.7V to 3.6V supply, consuming only 413mW, while delivering a typi- cal signal-to-noise ratio (SNR) of 58.5dB at an input fre- quency of 20MHz and a sampling rate of 105Msps. 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 MAX1180 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 MAX1180 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 MAX1180 is available in a 7mm ✕ 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range.
The MAX1180 is a 3.3 V, dual‑channel, 10‑bit analog‑to‑digital converter optimized for low‑power, high‑dynamic‑performance applications such as imaging, instrumentation, and digital communications. It features fully‑differential wideband track‑and‑hold inputs, a precision 2.048 V bandgap reference, and selectable output formats (two’s complement or offset binary).\n\nThe device is supplied in a 48‑pin TQFP‑EP package (7 mm × 7 mm) and operates over an extended temperature range of –40 °C to +85 °C. Typical power consumption is 125 mA in normal mode, 2.8 mA in sleep, and 1 µA in shutdown. The analog supply voltage range is 2.7 V to 3.6 V, and the differential input range is ±1.0 V.
