Mingjiada Supply ADI AD7894 And AD7895 Serial Analog To Digital Converter (ADC)

With the continuing growth in demand for high-precision, compact, low-power ADCs in industrial automation, instrumentation, process control and portable data acquisition equipment, Mingjiada Electronics has long been a supplier of the 【ADI】 AD7894 / AD7895 series of serial-to-analogue converters. Thanks to their high resolution, 200 kSPS sampling rate, 5 V single-supply operation and compact 8-pin package, these products have become a classic choice for industrial and embedded data acquisition systems.

I. AD7894 – True bipolar input, 5 V single-supply, 14-bit, serial 4.5 µs ADC in an 8-pin package
1. Details:
The AD7894 is a high-speed, 14-bit analogue-to-digital converter (ADC) powered by a single +5 V supply and available in a compact 8-pin SOIC package. The device incorporates a 5 microsecond (µs) successive approximation ADC, an on-chip sample-and-hold amplifier, an on-chip clock and a high-speed serial interface. The AD7894 outputs data via a high-speed serial interface port; this two-wire serial interface features a serial clock input and a serial data output, and the serial data within the device can be accessed via an external serial clock.
2. Key Features:
High-speed 14-bit ADC with a conversion time of 5 microseconds
8-pin SOIC package
5 V single-supply operation
High-speed, easy-to-use serial interface
On-chip sample-and-hold amplifier
High input impedance
Input range options:
±10 V (AD7894-10)
±2.5 V (AD7894-3)
