Rail-to-rail comparators swing speedily
Rail-to-rail comparators are designed for applications that require high speed, low power, rail-to-rail swing and high precision.
Analog Devices' ADCMP60x family of rail-to-rail comparators is designed for applications that require high speed, low power, rail-to-rail swing and high precision The comparator family supports all prevailing digital output stages - including LVDS, CML and TTL/CMOS - required by applications such as medical instruments, test and measurement, RF and telecommunications equipment

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The LVDS-compatible output stage, designed to drive any standard LVDS input, allows the ADCMP60x comparators to be coupled with FPGAs and ASSPs that feature high-speed inputs and achieve faster transition times.
The ADCMP60x family offers propagation delays ranging from 1 to 35ns with as little as 2.5ps RMS random jitter.
The ADCMP60x comparators offer rail-to-rail performance that is fully specified from 2.5 to 5.5V.
This is particularly beneficial at low voltages where previous generation fast rail-to-rail comparators experience dead zones at operating voltages below 2.7V.
Isolating the input and output supplies is important because parasitic coupling from the output to the input can cause instability when overdrive conditions are low.
Several members of the ADCMP60x family split the two supplies to provide a wide input signal range and reduce power consumption by as much as 50% compared with competitive offerings.
High-speed latch and programmable hysteresis features are provided in a single-pin control option, producing balanced input-to-output delays and eliminating oscillation issues.
The ADCMP60x comparators work well in applications with Analog Devices' family of direct digital synthesis products to generate programmable high-speed, low-jitter clocks.
They also complement ADI's high-speed log amps, such as the AD8318, for amplifying low-level RF burst pulses.
The ADCMP60x comparators are sampling now and will be available in full production quantities in September of 2006.
Priced from $0.58 to $2.35 in 1000-piece quantities, the comparators are available in SC-70, SOT-23, MSOP and LFCSP packages.
