The AD7904 / AD7914 / AD7924 are, respectively, 8-bit, 10-bit, and 12-bit, high speed, low power, 4-channel successive approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 8 MHz.The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily inter-face with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point. There are no pipeline delays associated with the part.The AD7904 / AD7914 / AD7924 use advanced design techniques to achieve very low power dissipation at maximum throughput rates. At maximum throughput rates, the AD7904 / AD7914 / AD7924 consume 2 mA maximum with 3 V supplies; with 5 V supplies, the current consumption is 2.7 mA maximum.Through the configuration of the control register, the analog input range for the part can be selected as 0 V to REFIN or 0 V to 2 × REFIN, with either straight binary or twos complement output coding. The AD7904 / AD7914 / AD7924 each feature four single-ended analog inputs with a channel sequencer to allow a pre-programmed selection of channels to be converted sequentially.The conversion time for the AD7904 / AD7914 / AD7924 is determined by the SCLK frequency, which is also used as the master clock to control the conversion.PRODUCT HIGHLIGHTS High Throughput with Low Power Consumption. The AD7904/AD7914/AD7924 offer throughput rates up to 1 MSPS. Four Single-Ended Inputs with Channel Sequencer. A consecutive sequence of channels can be selected, through which the ADC will cycle and convert on. Single-Supply Operation with VDRIVE Function. The AD7904/AD7914/AD7924 operate from a single 2.7 V to 5.25 V supply. The VDRIVE function allows the serial interface to connect directly to 3 V or 5 V processor systems, independent of VDD. Flexible Power/Serial Clock Speed Management. The conversion rate is determined by the serial clock, allowing the conversion time to be reduced by increasing the serial clock speed. The parts also feature two shutdown modes to maximize power efficiency at lower throughput rates. Current consumption is 0.5 µA maximum when in full shutdown. No Pipeline Delay. The parts feature a standard successive approximation ADC with accurate control of the sampling instant via the CS input and once-off conversion control.

The AD797 is a very low noise, low distortion operational amplifier ideal for use as a preamplifier. The low noise of 0.9 nV√Hz and low total harmonic distortion of -120 dB at audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles.Furthermore, the AD797's excellent slew rate of 20 V/µs and 110 MHz gain bandwidth make it highly suitable for low frequency ultrasound applications.The AD797 is also useful in IR and Sonar Imaging applications where the widest dynamic range is necessary. The low distortion and 16-bit settling time of the AD797 make it ideal for buffering the inputs to Sigma Delta ADCs or the outputs of high resolution DACs especially when they are used in critical applications such as seismic detection and spectrum analyzers. Key features such as a 50 mA output current drive and the specified power supply voltage range of ±5 to ±15 volts make the AD797 an excellent general purpose amplifier.APPLICATIONS Professional audio preamplifiers IR, CCD, and sonar imaging systems Spectrum analyzers Ultrasound preamplifiers Seismic detectors Σ-Δ ADC/DAC buffers

The AD7994 is a 4-channel, 10- and 12-bit, low power, successive approximation ADCs with an I2C-compatible interface. The parts operate from a single 2.7 V to 5.5 V power supply and feature a 2 µs conversion time. The parts contain a 4-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz.The AD7994 provides a two-wire serial interface which is compatible with I2C interfaces. The part comes in two versions, AD7994-0 and AD7994-1. Each version allows for a minimum of two different I2C addresses. The I2C interface on the AD7994-0 supports Standard and Fast I2C Interface Modes. The I2C interface on the AD7994-1 supports Standard, Fast and two High-Speed I2C Interface Modes.The AD7994 normally remain in a shutdown state while not converting, and power up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I2C write operations, or an automatic conversion interval mode selected through software control. The AD7994 require an external reference that should be applied to the REFIN pin and can be in the range of 1.2 V to VDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when the programmed high or low limits are violated by the conversion result. This output can be used as an interrupt.PRODUCT HIGHLIGHTS 2 µs conversion time with low power consumption. I2C-compatible serial interface with pin-selectable addresses. Two AD7993 / AD7994 versions allow five AD7993 / AD7994 devices to be connected to the same serial bus. The parts feature automatic shutdown while not converting to maximize power efficiency. Current consumption is 1 µA max when in shutdown mode. Reference can be driven up to the power supply. Out-of-range indicator that can be software disabled or enabled. One-shot and automatic conversion rates. Registers can store minimum and maximum conversion results.
