Description

The AD5512A / AD5542A are single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREFand is guaranteed monotonic, providing 1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of −40°C to +85°C (AD5542A) or −40°C to +125°C (AD5512A). Offering unbuffered outputs, the AD5512A/AD5542A achieve
a 1 μs settling time with low offset errors ideal for high speed open loop control.

Features

1. 12-bit resolution

2. 2.7 V to 5.5 V single-supply operation

3. Hardware CLRand LDACfunctions

4. 50 MHz SPI-/QSPI-/MICROWIRE-/DSP-compatible interface

5. Power-on reset clears DAC output to midscale

Applications:

1. Automatic test equipment

2. Precision source-measure instruments

3. Data acquisition systems

4. Medical and aerospace instrumentation

5. Communication equipment

Description

The VFC320 monolithic voltage-to-frequency and frequency-to-voltage converter provides a simple low cost method of convert ing analog signals into digital pulses. The digital output is an open collector and the digital pulse train repetition rate is proportional to the amplitude of the analog input voltage. Output pulses are compatible with TTL, and CMOS logic families.

High linearity (0.005%, max at 10kHz FS) is achieved with relatively few external components. Two external resistors and two external capacitors are required to operate. Full scale frequency and input voltage are determined by a resistor in series with –In and two capacitors (one-shot timing and input amplifier integration). The other resistor is a non-critical open collector pull-up (fOUTto +V CC ).

Features

1. HIGH LINEARITY : 12 to 14 bits
(1) ±0.005% max at 10kHz FS
(2) ±0.03% max at 100kHz FS
(3) ±0.1% typ at 1MHz FS

2. V/F OR F/V CONVERSION

3. 6-DECADE DYNAMIC RANGE

4. GAIN DRIFT: 20ppm/°C max

5. OUTPUT TTL/CMOS COMPATIBLE

Applications:

1. INEXPENSIVE A/D AND D/A CONVERTER

2. DIGITAL PANEL METERS

3. TWO-WIRE DIGITAL TRANSMISSION WITH NOISE IMMUNITY

3. FM MOD/DEMOD OF TRANSDUCER SIGNALS

4. PRECISION LONG TERM INTEGRATOR
