Product details

Overview

ADAQ7980BCCZ from Analog Devices is a 16-bit, 1 MSPS integrated data acquisition μModule subsystem combining SAR ADC, precision ADC driver, reference buffer, and power management in a single 5 mm × 4 mm LGA package. It delivers ±8 ppm INL, 91.5 dB SNR at 10 kHz, and ±0.06 mV zero error (typical), enabling high-accuracy measurement in space-constrained industrial and medical instrumentation.

For engineers reviewing the ADAQ7980BCCZ datasheet, ADAQ7980BCCZ pinout, ADAQ7980BCCZ application, or ADAQ7980BCCZ equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The ADAQ7980BCCZ integrates a 16-bit SAR ADC with a configurable ADC driver supporting unity-gain buffer or difference amplifier modes, a low-drift reference buffer (±0.013% gain error, 1.3 µV/°C zero drift), and an internal LDO regulator with dynamic power scaling. Its system-in-package architecture eliminates external passive component selection for signal conditioning.

It supports dual-supply (±7.7 V / −2.5 V) and single-supply (5 V) configurations, features SPI/QSPI/MICROWIRE-compatible serial interface with daisy-chain capability, and operates across −55°C to +125°C with 3500 V HBM ESD rating. The 24-lead LGA package includes exposed thermal pad for thermal management.

Pinout & Package

ADAQ7980BCCZ uses a 24-lead, 5 mm × 4 mm LGA (Land Grid Array) package with exposed thermal pad (pin 24). Pin numbering follows standard LGA convention: top-left corner = Pin 1, row-wise left-to-right, top-to-bottom.

Pin/Terminal	Circuit Role	Design Meaning

V+	Positive analog supply rail	Supplies ADC core and driver; range: 3.7 V to 7 V (dual) or 5 V (single); must be ≥ \|V−\| + 10 V.
V−	Negative analog supply rail	Supports bipolar input operation; range: −2.5 V to −0.2 V (dual) or 0 V (single); referenced to GND.
VIO	Digital I/O supply	1.7 V to 5.5 V logic interface; sets SPI voltage levels; independent of analog supplies for mixed-voltage systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar data acquisition subsystem applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADAQ7988BCCZ	500 kSPS maximum throughput, 16.5 mW typical power, identical pinout and feature set except lower speed and reduced dynamic power scaling duty cycle.	Better suited for lower-bandwidth, ultra-low-power applications where 1 MSPS is unnecessary; same PCB layout but firmware timing adjustments required.	Select ADAQ7988BCCZ when system sampling requirement is ≤500 kSPS and average power must stay below 17 mW.
LTC2378-16#PBF	Discrete 16-bit SAR ADC (no integrated driver/reference/LDO); requires external op-amp, reference, and power sequencing; 1 MSPS, ±1.5 ppm INL, 93.5 dB SNR.	Offers higher SNR and lower INL but demands full signal chain design, layout optimization, and validation effort - increases time-to-market by 6–12 weeks.	Choose LTC2378-16#PBF only when absolute best-in-class performance justifies added design complexity and board area.

Compared with ADAQ7980BCCZ, ADAQ7988BCCZ trades speed for lower power in identical hardware, while LTC2378-16#PBF delivers marginally better specs at the cost of full external signal conditioning - making ADAQ7980BCCZ optimal for rapid deployment of robust, medium-speed precision DAQ systems.

FAQ

What is the maximum sampling rate supported by the ADAQ7980BCCZ?

The ADAQ7980BCCZ supports a maximum throughput of 1 MSPS under dual-supply conditions with VIO ≥ 3.0 V. At lower VIO (≥1.7 V), the rate drops to 833 kSPS. This is specified in Table 2 of the Rev. B datasheet and confirmed across both dual- and single-supply configurations. The ADAQ7980BCCZ achieves this rate while maintaining 16-bit no-missing-codes performance and 91.5 dB SNR.

Does the ADAQ7980BCCZ require external passive components for basic operation?

No - the ADAQ7980BCCZ integrates all critical passive components required for specified performance, including precision matching capacitors for the SAR ADC, RC filter elements for the ADC driver, and decoupling networks for internal regulators. External components are limited to bulk decoupling capacitors (e.g., 10 µF on VDD) and optional RC filters on IN+/IN− for anti-aliasing. This integration is a defining feature of the μModule architecture.

Can the ADAQ7980BCCZ operate from a single 5 V supply?

Yes - the ADAQ7980BCCZ supports single-supply operation with VDD = V+ = 5.0 V, V− = 0 V, and VREF = 3.3 V. In this mode, it maintains 16-bit resolution, ±8 ppm INL, and 86.5 dB SNR at 10 kHz, as verified in Table 4 of the datasheet. Input common-mode range shifts to 0.15 V to 3.3 V, and ADC driver slew rate reduces to 31 V/µs - all fully characterized and supported.

How does the power-down functionality work on the ADAQ7980BCCZ?

The ADAQ7980BCCZ provides three independent power-down controls: PD_AMP disables the ADC driver (reducing current to 56 µA), PD_REF disables the reference buffer, and PD_LDO disables the internal LDO. Asserting all three yields 14 µA total standby current. Turn-on time is 2–7.25 µs, enabling rapid wake-up for burst-mode acquisition. These signals are CMOS-compatible and referenced to VIO.

Is the ADAQ7980BCCZ pin-compatible with other devices in the ADAQ798x family?

Yes - the ADAQ7980BCCZ and ADAQ7988BCCZ share identical 24-lead LGA package footprints, pin assignments, and interface protocols. They differ only in maximum throughput (1 MSPS vs 500 kSPS), power consumption, and minor AC performance trade-offs. This allows direct hardware reuse and firmware adaptation between the two variants without PCB revision.
