Texas Instruments ADS1610EVM

Overview

ADS1610EVM from Texas Instruments is a stand-alone evaluation board for the ADS1610 16-bit, 10-MSPS delta-sigma analog-to-digital converter. It provides full data-sheet performance with onboard signal conditioning (THS4503 differential driver), precision reference generation (THS4031-based, factory-set to 3-V differential reference), and parallel digital interface compatible with TMS320 DSP platforms. Designed for high-fidelity data acquisition in test & measurement systems.

For engineers reviewing the ADS1610EVM datasheet, ADS1610EVM pinout, ADS1610EVM application, or ADS1610EVM equivalent, this page delivers verified layout guidance, power supply requirements (±7 V, +5 V, +3 V), jumper-configurable clock source (60-MHz oscillator or external SMA input), and interface mapping for TSW1100 capture and C6713 DSK integration.

Technical Context

The ADS1610EVM implements a complete signal chain for the ADS1610 ADC: differential analog input via THS4503 amplifier (gain = 2, 2.5-V common-mode), on-board reference generation using three THS4031 op-amps (adjustable VREFP/VMID/VREFM), and antialiasing filtering (24-Ω + 300-pF). The modulator clock path supports either the onboard 60-MHz oscillator (X1) or user-supplied clock via SMA J4, with W3 jumper selection.

Digital control uses SW1 DIP switch for M0/M1 mode configuration and power-down, while address decoding (J19) enables four memory-mapped base addresses (0xA0000000–0xA000000C) for host processor interfacing. Data output is buffered 16-bit parallel (D0–D15) across J2 and J18 connectors, with DRDY_OUT and OTR_INT signals routed to J10/P10 for interrupt and out-of-range monitoring.

FAQ

What is the primary function of the ADS1610EVM?

The ADS1610EVM is a fully featured evaluation board designed specifically for the ADS1610 16-bit, 10-MSPS delta-sigma analog-to-digital converter. Its purpose is to enable rapid characterization, performance validation, and system-level integration of the ADS1610 in real-world applications. The ADS1610EVM includes all necessary signal conditioning, reference generation, clocking, and digital interface circuitry to deliver data-sheet specifications without additional hardware.

Which power supplies are required to operate the ADS1610EVM?

The ADS1610EVM requires three independent power rails: ±7 Vdc for optimal analog front-end and reference circuitry performance (applied at J11), +5 Vdc for the ADS1610 analog and clock supplies (J12 and J13), and +3 Vdc for the digital section including buffers and address decoders (J1). All voltages must be clean, well-regulated, and properly bypassed per the layout guidelines in the SLAU180A user's guide.

How does the ADS1610EVM connect to a host processor or data capture system?

The ADS1610EVM connects via three key interfaces: J2 (40-pin) mates directly with TI's TSW1100 data capture board; J18 (40-pin) supports breadboard, ribbon cable, or 5-6K interface board connections; and J10/P10 provides control signals (HOST_CS, HOST_WR, HOST_RD, HOST_A2/A3, DRDY_OUT, OTR_INT) for memory-mapped interfacing to DSPs like the TMS320C6713. Base address is configurable via J19 jumpers.

Can the reference voltage on the ADS1610EVM be adjusted, and what is the impact?

Yes, the ADS1610EVM allows adjustment of VREFP, VMID, and VREFM using trim potentiometers R37, R38, and R40. Factory settings yield a 3-V differential reference (VREFP = 4 V, VMID = 2.5 V, VREFM = 1 V), enabling 86 dBFS SNR. Reducing reference voltage trades SNR for reduced full-scale range - e.g., 2.5-V reference yields 85 dBFS, and 2-V reference yields 83 dBFS - as documented in Table 1 of the SLAU180A user's guide.

What clock sources does the ADS1610EVM support, and how is selection performed?

The ADS1610EVM supports two clock sources for the ADS1610 modulator: the onboard 60-MHz oscillator (X1) or an external clock applied via SMA connector J4. Selection is controlled by jumper W3: pins 1–2 enables the onboard oscillator, while pins 2–3 routes the external clock. When using external clocking, R9 (50-Ω termination) may be installed, and clock amplitude must be halved if sourced from a 50-Ω driver to avoid overdriving the CLK input.
