12bit ADC claims speed record
Maxim Integrated Products is claiming a new 12bit sampling-speed standard with the introduction of the MAX1215, a 12bit 250Msample/s analogue-to-digital convertor (ADC).
Maxim Integrated Products is claiming a new 12bit sampling-speed standard with the introduction of the MAX1215, a 12bit 250Msample/s analogue-to-digital convertor (ADC) At 250Msample/s, this new ADC has the world's fastest sample rate at the 12bit level, and delivers outstanding dynamic performance over input frequencies as high as 300MHz

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.
The MAX1215 is ideal for designers who need to implement higher order power-amplifier predistortion, because the 250Msample/s update rate allows them to sample wider bandwidths with greater dynamic range than could have been sampled before.
The device also consumes 34% less power than the closest competitor, whose sampling rate is only 210Msample/s.
The MAX1215 achieves a spurious-free dynamic range (SFDR) of 74dBc.
It has an excellent signal-to-noise ratio (SNR) of 66dB at 10MHz which remains flat (within 2dB) for input tones up to 300MHz.
Such excellent dynamic performance makes this device suitable for wideband applications like cable-head end receivers and power-amplifier predistortion in cellular basestations.
This high-speed, 12bit ADC runs on a single 1.8V supply.
The analogue input is designed for either differential or single-ended operation and can be AC or DC coupled.
The selectable on-chip, divide-by-two clock circuit reduces the phase noise of the input clock source.
The digital outputs are LVDS compatible, and the data format can be selected as either two's complement or offset binary.
The MAX1215 completes a family of pin-compatible 8, 10 and 12bit parts that can sample up to 250Msample/s.
Like the rest of the family, the MAX1215 is in production and available in a space-saving, 68-pin TQFN-EP package specified for the industrial temperature range (-40 to +85C).
An evaluation kit is available to shorten design time.
Pricing starts at $47.50 (1000-up, FOB USA).
