The MAX1438 is an octal, 12-bit analog-to-digital converter (ADC) with fully differential inputs, a pipelined architecture, and digital error correction incorporating a fully differential signal path. This ADC is optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital communications applications. The MAX1438 operates from a 1.8V single supply and consumes only 913mW (114mW per channel) while delivering a 69.9dB (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1438 features a power-down mode for idle periods. An internal 1.24V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of an external reference for applications requiring increased accuracy or a different input voltage range. The reference architecture is optimized for low noise. A single-ended clock controls the data-conversion process. An internal duty-cycle equalizer compensates for wide variations in clock duty cycle. An on-chip PLL generates the high-speed serial low-voltage differential signal (LVDS) clock. The MAX1438 has self-aligned serial LVDS outputs for data, clock, and frame-alignment signals. The output data is presented in two’s complement or binary format. The MAX1438 offers a maximum sample rate of 65Msps. See the Pin-Compatible Versions table below for lower-speed versions. This device is available in a small, 14mm x 14m.
