Maxim 105MSPS Manuals

The MAX1449 is a 3.3V, 10-bit analog-to-digital converter (ADC) with fully differential input, pipelined 10-stage ADC architecture with wideband track-and-hold (T/H), and digital error correction incorporating a fully differential signal path. The ADC is optimized for low-power, high-dynamic performance in imaging and digital communications applications. The converter operates from a single 2.7V to 3.6V supply, consuming only 186mW while delivering a 58.5dB (typ) signal-to-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a -3dB 400MHz bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1449 features a 5µA power-down mode for idle periods. An internal 2.048V precision bandgap reference is used to set the ADC’s full-scale range. A flexible reference structure allows the user to supply a buffered, direct, or externally derived reference for applications requiring increased accuracy or a different input voltage range. Lower speed, pin-compatible versions of the MAX1449 are also available. Refer to the MAX1444 data sheet for a 40Msps version, the MAX1446 data sheet for a 60Msps version, and the MAX1448 data sheet for 80Msps. The MAX1449 has parallel, offset binary, CMOS-com- patible, three-state outputs that can be operated from 1.7V to 3.6V to allow flexible interfacing. The device is available in a 5mm x 5mm 32-pin TQFP package and is specified over the extended i

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.
