The MAX1183 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 MAX1183 is optimized for low-power, high dynamic performance applications in imaging, instrumen- tation, and digital communication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 120mW while delivering a typical signal-to-noise ratio (SNR) of 59.6dB at an input frequency of 20MHz and a sampling rate of 40Msps. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The convert- ers may also be operated with single-ended inputs. In addition to low operating power, the MAX1183 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 this internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1183 features parallel, CMOS-compatible three-state outputs. The digital output format can be 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 MAX1183 is available in a 7mm ✕ 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to 125°C) temperature range.
The MAX1183 is a 3 V, dual 10‑bit analog‑to‑digital converter featuring fully differential wideband track‑and‑hold inputs and parallel CMOS‑compatible three‑state outputs. It operates from a single 2.7 V to 3.6 V supply and includes a precision 2.048 V bandgap reference that can be used internally or replaced with an external reference.
Key specifications include a 40 Msps maximum conversion rate, 59.6 dB SNR at 20 MHz input, 120 mW typical power consumption in normal mode, and a 48‑pin TQFP‑EP package rated for –40 °C to +85 °C. The device offers selectable output format (two’s complement or offset binary) and supports low‑power sleep and shutdown modes.
