This document is AD7712 datasheet, which introduces the features of AD7712. AD7712 is a 24-bit single-channel analog input ADC chip supporting 2.5V and 5V power supply, with low power consumption (25mW typ) and high accuracy (±0.0015%).

The AD7713 is a 24-bit low power AD converter from Analog Devices, with 3-channel programmable gain front end, which can be used in loop powered (smart) transmitters, RTD transducers, process control and portable industrial instruments.

The AD7703 is a 20-bit ADC that uses a S-D conversion technique. It features a monolithic 16-bit ADC, 0.0015% linearity error, on-chip self-calibration circuitry, programmable low-pass filter, 0V to +2.5V or -2.5V analog input range, 4kSPS output data rate, flexible serial interface, and ultralow power consumption.

AD7711A is a 24-bit analog front-end from AD company. It uses sigma-delta conversion technique, and can be applied to low frequency measurement applications. The device can directly accept the signal from the transducer and convert it into a serial digital signal.

AD1871 is a stereo audio ADC produced by Analog Devices. It supports 24-bit, 96kHz, multibit Σ-Δ modulator, with “Perfect Differential Linearity Restoration” feature, which can reduce idle tones and noise floor. It supports 256/512 and 768 fS master clocks, flexible serial data port allows right-justified, left-justified, I2S compatible and DSP serial port modes. It can be cascaded (up to four devices) from a single DSP SPORT device, and can be controlled via SPI compatible serial port or optional control pins.

AD1877 is a single-supply, 16-bit single-channel ADC from Analog Devices. It features a fourth-order, 64-times oversampling modulator and a three-stage linear-phase decimator that effectively reduces quantization noise. The ADC has a dynamic range of 92 dB, a S/(THD+N) of 90 dB, and supports 256fs or 384fs input clocks. It consumes less than 100 mW of power and supports power-down mode. The ADC also includes input overrange indication, an on-chip voltage reference, and a flexible serial output interface. It is available in a 28-lead SOIC package.

The document describes the features and characteristics of Analog Devices' AD7741/AD7742 single-channel and multi-channel synchronous voltage-to-frequency converters. The product is available in versions with a single-ended input channel (AD7741) and differential or pseudo-differential input channels (AD7742). It has an integral nonlinearity of 0.012%, achieving a maximum frequency output of 2.75 MHz (AD7742) and 1.35 MHz (AD7741). The product is suitable for low-cost analog-to-digital conversion and signal isolation applications.

The AD7740 is a low-cost, ultrasmall synchronous Voltage-to- Frequency Converter (VFC). It works from a single 3.0 V to 3.6 V or 4.75 V to 5.25 V supply consuming 0.9 mA. The AD7740 is available in an 8-lead SOT-23 and also in an 8-lead microSOIC package. Small package, low cost and ease of use were major design goals for this product. The part contains an on-chip 2.5 V bandgap reference but the user may overdrive this using an external voltage.

Low Cost Monolithic Voltage-to-Frequency Converter

The ADVFC32 is a low-cost monolithic voltage-to-frequency (V/F) converter or frequency-to-voltage (F/V) converter with good linearity and high operating frequency.
