Circuit Function and Benefits: The circuit shown in Figure 1 is a highly integrated, 16-bit, 1 MSPS, multiplexed, 8-channel, flexible digital acquisition system (DAS) with integrated programmable gain instrumentation amplifier (PGIA) capable of Handle a full range of industrial grade signals. A +5 V single supply powers the circuit. The high efficiency, low ripple boost converter produces ±15 V and can handle differential input signals up to ±24.576 V (±2 LSB INL maximum, ±0.5 LSB DNL typical) . For high precision applications, this compact, economical circuit provides high accuracy and low noise performance. A data acquisition system based on a successive approximation register (SAR) integrates a true high-impedance differential input buffer, so no additional buffering is required; buffering is typically used to reduce SAR analog-to-digital converters (ADCs) based on capacitive digital-to-analog converters (DACs) The resulting recoil. In addition, the circuit has high common-mode rejection and eliminates the need for an external instrumentation amplifier; instrumentation amplifiers are often used in applications where common-mode signals are common.

The ADAS3022 is a complete 16-bit, 1 MSPS data acquisition system that integrates an 8-channel, low-leakage multiplexer; a programmable gain instrumentation amplifier stage with high common-mode rejection; and a precision low-drift 4.096 V reference Voltage source; a reference buffer; and a high performance, delay-free, 16-bit SAR ADC. The ADAS3022 reduces power consumption at the end of each conversion cycle, so the operating current and power are linearly proportional to throughput. It is ideal for low sample rate battery powered applications. The ADAS3022 integrates eight inputs and one COM input; this COM input can be configured as eight single-ended channels, eight channels referenced to the same reference voltage, four differential channels, or different combinations of single-ended and differential channels. In the circuit shown in Figure 1, the ADR434 low-noise reference voltage buffered by the AD8031 op amp provides a reference voltage. The AD8031 is capable of driving dynamic loads in a fast recovery mode, making it ideal for use as a reference buffer.
The ADP1613 is a DC-DC boost converter with an integrated power switch that provides the ADAS3022 with an on-chip input multiplexer and a ±15 V high-voltage power supply for a programmable gain instrumentation amplifier without affecting the performance of the ADAS3022. This circuit uses a combination of ADAS3022, ADP1613, ADR434, and AD8031 precision devices to provide both high accuracy and low noise performance.
Circuit Description: The complete DAS on the first single chip can be converted at up to 1 MSPS and accept differential analog input signals up to ±24.576 V. The device requires a high voltage bipolar supply: ±15 V (VDDH and VSSH), +5 V (AVDD and DVDD), and +1.8 V to +5 V (VIO). The ADAS3022 simplifies the design challenges of precision 16-bit, 1 MSPS DAS without the need for signal buffering, level shifting, amplification, noise suppression, and other analog signal conditioning in standard solutions. In addition, the ADAS3022 offers better timing and noise performance at higher data rates, smaller sizes, faster time-to-market, and lower prices.
The ADAS3022 integrates PGIA to set gains of 0.16, 0.2, 0.4, 0.8, 1.6, 3.2, and 6.4, and it can handle fully differential input ranges of ±24.576 V, ±20.48 V, ±10.24 V, ±5.12 V, respectively. ±2.56 V, ±1.28 V, and ±0.64 V. The input range is referenced to the internal 4.096 V reference. It measures the input range of pseudo-differential, unipolar, and bipolar with respect to the input voltage on the COM pin. In the circuit shown in Figure 1, the external reference is provided by the 4.096 V ADR434. The ADR434 features high accuracy, low power consumption (800 μA operating current), low noise, ±0.12% maximum initial error, and excellent temperature stability. The AD8032 low-power op amps used to buffer external reference voltages are ideal for battery-powered systems with high bandwidth requirements and high-speed systems with high component density and low power requirements. The ADAS3022 digital interface consists of asynchronous inputs (CNV, RESET, PD, and BUSY) and 4-wire serial interfaces (CS, SDO, SCK, and DIN) that are compatible with SPI, FPGA, or DSP for readback of conversion results and read configuration registers. composition.
