Original Press Release:
12-Bit, 3Msps SAR ADC Dissipates Only 7.2mW in Tiny Thin SOT23 Package
MILPITAS, CA - April 30, 2008 - Linear Technology Corporation introduces the LTC2366, a 12-bit successive approximation register (SAR) ADC that outputs data at up to 3Msps in tiny 6- and 8-lead TSOT-23 packages. Operating from a single 2.35V to 3.6V supply, the LTC2366 consumes only 7.2mW at the maximum output rate, a 20% power savings over the nearest competitor. With its tiny footprint and very low power dissipation, the LTC2366 is ideal for a wide variety of portable and space-constrained applications, including medical devices, communication systems, and industrial monitors.
The LTC2366 is Linear's fastest offering in a family of five TSOT-23 pin- and software-compatible ADCs. The LTC2365 output data rate is guaranteed up to 1Msps and the LTC2362 up to 500ksps. For lower speeds, the LTC2361 is guaranteed up to 250ksps and the LTC2360 up to 100ksps. Power is optimized for each sample rate, as the LTC2360 draws just 1.5mW at 100ksps. Power dissipation can be further decreased with a shutdown mode that reduces the supply current to 2uA (max), saving battery life. All five ADCs are offered in industry standard 6-pin TSOT-23 packages, as well as 8-pin TSOT-23 packages that include an external reference pin and a digital output supply pin (OVDD) that can range between 1V and VDD. With guaranteed specifications across the -40°C to +125°C temperature range, the LTC2366, LTC2365, LTC2362, LTC2361, and LTC2360 can be used for monitoring precision DC or AC signals in a variety of applications, including automotive.
Communicating via a serial SPI/QSPI/Microwire-compatible interface, these ADCs offer no data latency and achieve excellent DC specifications of +/-1LSB INL and +/-1LSB DNL. These converters also excel when digitizing AC signals. The LTC2366 measures 72dB SNR, -80dB THD, and 82dB SFDR at a 1MHz input frequency.
The LTC2360-LTC2362 and LTC2365/LTC2366 are all available today in commercial, industrial, and automotive temperature grades. Pricing begins at $1.25 for 1,000-piece quantities.
