MAXIM MAX1421 12-Bit 40Msps 3.3V Low-Power ADC with Internal Reference handbook
Update: 29 September, 2023
The MAX1421 is a 3.3V, 12-bit analog-to-digital converter (ADC) with a fully-differential input, pipelined, 12-stage ADC architecture. It features wideband track-and-hold (T/H) and digital error correction with a fully-differential signal path. The MAX1421 is designed for low-power, high-dynamic performance applications in imaging and digital communications. It operates from a single 3.3V supply, consuming only 188mW of power while delivering a typical signal-to-noise ratio (SNR) of 66dB at an input frequency of 15MHz and a sampling frequency of 40Msps. The fully-differential input stage has a small signal -3dB bandwidth of 400MHz and can be operated with single-ended inputs. It uses an internal 2.048V precision bandgap reference to set the full-scale range of the ADC. The reference structure is flexible and can accommodate an internal or externally applied buffered or unbuffered reference for applications requiring increased accuracy or a different input voltage range. In addition to low operating power, the MAX1421 offers two power-down modes: reference power-down and shutdown mode. In reference power-down mode, the internal bandgap reference is deactivated, resulting in a typical 2mA supply current reduction. For idle periods, a full shutdown mode is available to maximize power savings. The MAX1421 provides parallel, offset binary, CMOS-compatible three-state outputs. It is available in a 7mm x 7mm, 48-pin TQFP package.
