Maxim Integrated MAX1446GHJ

Description
The MAX1446 is a 10-bit, 60Msps, 3.0V, low-power analog-to-digital converter (ADC) with an internal reference. It features a fully differential input, a pipelined 10-stage ADC architecture with digital error correction, and a wideband track and hold (T/H) incorporating a fully differential signal path. The ADC is optimized for low-power, high dynamic performance applications in imaging and digital communications. It operates from a single 2.7V to 3.6V supply, consuming only 90mW while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a 400MHz, -3dB bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1446 features a 5μA power-down mode for idle periods. An internal 2.048V precision bandgap reference is used to set the ADC 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.
