Eight-channel ADC saves space onboard
The LTC2308 provides a high level of integration to reduce board area and total system cost, making it ideal for portable instruments and space-constrained designs.
New from Linear Technology, the LTC2308 is a 12bit analogue-to-digital convertor (ADC) that measures eight single-ended input channels, four differential input channels, or combinations of both for digitising multiple data acquisition signals with a single chip The LTC2308 features an internal eight-channel multiplexer and communicates via an SPI-compatible serial interface at throughput rates up to 500Ksample/s

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
With the combination of an internal reference and a tiny 4 x 4mm QFN-24 package, the LTC2308 provides a high level of integration to reduce board area and total system cost, making it ideal for portable instruments and space-constrained designs.
The LTC2308 operates from a single 5V supply, drawing only 17mW at the 500Ksample/s throughput.
Power dissipation can be further decreased with two shutdown modes.
Nap mode reduces the power to 1.15mW at 1Ksample/s, and sleep mode shuts down all internal circuitry and reduces the power to 35uW.
The LTC2308 measures unipolar or bipolar input signals, achieving excellent DC specifications, including +/-2mV (maximum) zero-scale error and +/-4LSB (maximum) full-scale error.
The LTC2308 excels when digitising AC input signals, measuring 73dB SINAD and -88dB THD at 1kHz.
A separate digital output voltage supply allows users to configure the serial data output for power supplies ranging from 3 to 5V logic.
The LTC2308 is available today in both commercial and industrial temperature grades, beginning at US $2.95 in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
