12-Bit, 60Msps, +3.3V, Low-Power ADC with Internal Reference
General Description
The MAX1420, +3.3V, 12-bit analog-to-digital converter (ADC) features a fully-differential input, pipelined, 12stage ADC architecture with wideband track-and-hold (T/H) and digital error correction, incorporating a fullydifferential signal path. The MAX1420 is optimized for low-power, high dynamic performance applications in imaging and digital communications. The converter operates from a single +3.3V supply, and consumes only 221mW. The fully-differential input stage has a small signal -3dB bandwidth of 400MHz and may be operated with single-ended inputs. An internal +2.048V precision bandgap reference sets the full-scale range of the ADC.
