MAX1420
12-Bit, 60Msps, +3.3V, Low-Power ADC with Internal Reference
|
Status
Description
The MAX1420, 3.3V, 12-bit analog-to-digital converter (ADC) features a fully-differential input, pipelined, 12-stage ADC architecture with wideband track-and-hold (T/H) and digital error correction, incorporating a fully-differential 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. A flexible reference structure accommodates an internal reference, or externally applied buffered or unbuffered reference for applications that require increased accuracy and a different input voltage range.
In addition to low operating power, the MAX1420 features two power-down modes: reference power-down and shutdown mode. In reference power-down, the internal bandgap reference is deactivated, which results in a typical 2mA supply current reduction. A full shutdown mode is available to maximize power savings during idle periods.
The MAX1420 provides parallel, offset binary, CMOS-compatible three-state outputs.
The MAX1420 is available in a 7mm x 7mm x 1.4mm, 48-pin TQFP package, and is specified over the commercial (0°C to +70°C) and the extended industrial (-40°C to +85°C) temperature range.
Pin-compatible lower speed versions of the MAX1420 are also available. Please refer to the MAX1421 data sheet for 40Msps and the MAX1422 data sheet for 20Msps.
