The HMCAD1520, HMCAD1511, and HMCAD1510 A/D converters feature integrated functions which are ideal for digital storage oscilloscope applications up to 4 Gsamples/s. They integrate crosspoint switches that allow switching between quad-, dual-, and single-channel modes, while integrated 1 to 8 x clock dividers keep the input clock frequency constant when the number of channels is changed.
The HMCAD1511 features 8-bit resolution at 1 Gsample/s and a power consumption of 710 mW. A 13-bit internal resolution allows up to 32 x (30 dB) of digital gain without missing codes, allowing the user to replace analog gain circuitry with digital gain settings.
The HMCAD1520 provides up to 12-bit resolution at up to 640 Msamples/s, while the HMCAD1510 features 8-bit resolution up 500 Msamples/s and consumes the lowest power in the industry at 295 mW, making it an ideal choice for high-performance handheld battery-powered oscilloscopes. All three ADCs can be evaluated with the Hittite EasySuite evaluation kits, EKIT01-AD1520, EKIT-AD1511, and EKIT-AD1510, which are based on Xilinx FMC (FPGA Mezzanine Card) SP601 standard motherboards and feature Hittite evaluation boards with on-board ADCs connected to the Xilinx board through an FMC connector. (Ea/10: HMCAD1520, $87.10; HMCAD1511, $60.65; HMCAD1510, $43.75 — available now.)
