The AD7170 is a very low power 12-bit analog-to-digital converter (ADC). It contains a precision 12-bit sigma-delta (?-?) ADC and an on-chip oscillator. Consuming only 135 ?A, the AD7170 is particularly suitable for portable or battery operated products where very low power is a requirement. The AD7170 also has a power-down mode in which the device consumes 5 ?A, thus increasing the battery life of the product.For ease-of-use, all the features of the AD7170 are controlled by dedicated pins. Each time a data read occurs, eight status bits are appended to the 12-bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer.The output data rate of the AD7170 is 125 Hz, whereas the settling time is 24 ms. The AD7170 has one differential input and a gain of 1. This is useful in applications where the user needs to use an external amplifier to implement system-specific filtering or gain requirements.The AD7170 operates with a power supply from 2.7 V to 5.25 V. It is available in a 10-lead LFCSP package.The AD7171 is a 16-bit version of the AD7170. It has the same feature set as the AD7170 and is pin-for-pin compatible.INTERFACE 2-wire serial (read-only device) SPI compatible Schmitt trigger on SCLKAPPLICATIONS Pressure measurement Industrial process control Portable instrumentation

The AD607 is a 3 V low power receiver IF subsystem for operation at input frequencies as high as 500 MHz and IFs from 400 kHz to 12 MHz. It consists of a mixer, IF amplifiers, I and Q demodulators, a phase-locked quadrature oscillator, and a biasing system with external power-down. The AD607?s low noise, high intercept mixer is a doubly balanced Gilbert cell type. It has a nominal ?15 dBm input referred 1 dB compression point and a ?8 dBm input referred third order intercept. The mixer section of the AD607 also includes a local oscillator (LO) preamplifier, which lowers the required LO drive to ?16 dBm. In MGC operation, the AD607 accepts an external gain-control voltage input from an external AGC detector or a DAC.The I and Q demodulators provide in-phase and quadrature baseband outputs to interface with Analog Devices? AD7013 (IS54, TETRA, MSAT) and AD7015 (GSM) baseband converters. A quadrature VCO phase-locked to the IF drives the I and Q demodulators. The I and Q demodulators can also demodulate AM; when the AD607?s quadrature VCO is phase-locked to the received signal, the in-phase demodulator becomes a synchronous product detector for AM. The VCO can also be phase-locked to an external beat-frequency oscillator (BFO), and the demodulator serves as a product detector for CW or SSB reception. Finally, the AD607 can be used to demodulate BPSK using an external Costas Loop for carrier recovery.APPLICATIONS GSM, CDMA, TDMA, and TETRA Receivers Satellite Terminals Battery-Powered Communications Receivers
