The AD7112BN is a dual 17-bit logarithmic digital-to-analog converter (DAC) from Analog Devices. It uses an R-2R architecture to provide accurate attenuation control, making it suitable for audio and instrumentation applications where logarithmic scaling is required. The device features a parallel data interface (8-bit DB0-DB7, CS, WR) and operates from a single 5V supply (4.75V to 5.25V).
The AD7112BN includes two independent DAC channels, each with its own feedback and input resistors. Key electrical characteristics include a typical input resistance of 12 kΩ and a typical feedback resistance of 12.5 kΩ. The device offers a gain error of ±0.15 dB max at +25°C and an output leakage current of ±50 nA max at +25°C.
The AD7112BN is housed in a 20-pin PDIP package (20-DIP, 0.300" body width) and supports through-hole mounting. It is specified for operation over the industrial temperature range of -40°C to +85°C. The device is RoHS3 compliant and has an MSL rating of 1 (unlimited).
The AD7112BN has a resolution of 17 bits.
The AD7112BN has 2 DAC channels.
The AD7112BN operates from -40°C to +85°C.
The AD7112BN is available in a 20-DIP (0.300", 7.62mm) package, also known as 20-PDIP.
The AD7112BN requires a VDD supply of 4.75V to 5.25V.
The AD7112BN uses a parallel data interface (8-bit DB0-DB7, CS, WR).
The AD7112BN is listed as RoHS3 Compliant, though this is unverified.
