Description

The DAC8562, DAC856x, DAC816x, and DAC756x are low-power, voltage-output, dual-channel, 16-, 14-, and 12-bit digital-to-analog converters (DACs), respectively. These devices include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA at the VREFIN/VREFOUT pin. These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three-wire serial interface that operates at clock rates up to 50 MHz. The interface is compatible with standard SPI™, QSPI™, Microwire, and digital signal processor (DSP) interfaces. The DACxx62 devices incorporate a power-on-reset circuit that ensures the DAC output powers up at zero scale until a valid code is written to the device, whereas the DACxx63s similarly power up at mid-scale. These devices contain a power-down feature that reduces current consumption to typically 550 nA at 5 V. The low power consumption, internal reference, and small footprint make these devices ideal for portable, battery-operated equipment.

Part Number: AD7452

Function: Differential Input, 555 kSPS, 12-Bit ADC

Package: 8-Lead SOT-23 Type

Manufacturer: Analog Devices

Pinouts:

 

Description

The AD7452 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter that features a fully differential analog input. This part operates from a single 3 V or 5 V power supply and features throughput rates up to 555 kSPS. The part contains a low noise, wide bandwidth, differential track-and-hold amplifier (T/H) that can handle input frequencies up to 3.5 MHz. The reference voltage is applied externally to the VREFpin and can be varied from 100 mV to 3.5 V depending on the power supply and what suits the application. The value of the reference voltage determines the common-mode voltage range of the part. With this truly differential input structure and variable reference input, the user can select a variety of input ranges and bias points.
