Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
When configured as an upconvertor, this single IC provides 39dBm of IIP3, 71dBc of LO +/-2IF suppression, and a conversion loss of only 6dB.
As a downconvertor, the MAX2029 delivers equally impressive performance with 36.5dBm of IIP3, 27dBm of IP1dB, 6.5dB of conversion loss, and a 6.7dB noise figure.
In addition, it exhibits excellent 2nd- and 3rd-order spurious suppression.

According to Maxim Integrated Products, the MAX2247 is the industry's smallest silicon germanium linear power amplifier for 2.4GHz WLAN applications.
Touch-screen controllers feature ESD protection
The MAX1233 and MAX1234 are programmable four-wire touch-screen controllers.
The MAX2029 is ideal for 815 to 1000MHz WCDMA, GSM850/GSM900 Edge, cdma2000, and iDEN basestation applications in which high linearity and a low noise figure are critical for enhanced receiver and transmitter performance.
As a complete SiGe up-/downconvertor, the MAX2029 integrates a state-of-the-art, double-balanced mixer core with an LO amplifier, two baluns, an LO switch, plus dozens of discrete components.
This integration reduces the total board space used by the mixer by 40%, and reduces the discrete part count by 33%.
The MAX2029's outstanding 2RF-2LO performance of 72dBc (with a -10dBm RF tone) also eases the filtering requirements of close-in harmonics, thus enabling simpler and more cost-effective filter designs.
This mixer offers an exceptionally wide, DC to 250MHz IF frequency range with a 570MHz to 900MHz, low-side LO injection range.
It supports frequency hopping with an integrated SPDT LO switch that has switching speeds typically less than 50ns and 53dB of LO1-to-LO2 isolation.
The onboard 0dBm drive, LO buffer provides +/-3dB drive-variance control, thus ensuring stable gain, NF and IIP3 performance over temperature, supply, and input power.
The MAX2029 has excellent gain-variation performance of +/-0.2dB over the -40 to +85C industrial temperature range.
The IIP3 spread is similarly impressive at +0.4dB/-0.6dB over temperature.
The MAX2029 is packaged in a compact, 5 x 5mm, 20-pin TQFN.
The package is pin compatible with the MAX2039, MAX2041, MAX2042 and MAX2044 series of 1700 to 2200, 1700 to 3000, 2300 to 2700, and 3200 to 3900MHz mixers, making this entire family of passive upconvertors and downconvertors ideal for applications in which a common PC-board layout is used for multiple wireless-infrastructure frequency bands.
Lead-free packaging is also available.
Prices start at US $6.15 (1000-up).
