Product details
Overview
AD7610BCPZ from Analog Devices is a 16-bit, 250 kSPS PulSAR® successive approximation register (SAR) ADC with programmable unipolar/bipolar input ranges (0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V), integrated 5 V reference (±3 ppm/°C drift), and dual parallel/serial (SPI-/QSPI™-/MICROWIRE™-/DSP-compatible) interface. It delivers ±1.5 LSB max INL, 94 dB SNR at 2 kHz, and operates across −40°C to +85°C in industrial data acquisition systems.
For engineers reviewing the AD7610BCPZ datasheet, AD7610BCPZ pinout, AD7610BCPZ application, or AD7610BCPZ equivalent, key selection considerations include its hardware/software-configurable input range, no-pipeline-delay SAR architecture, iCMOS® high-voltage process enabling ±15 V supplies, on-chip temperature sensor output (311 mV @ 25°C), and dual 48-lead LQFP/LFCSP package support.
Technical Context
The AD7610BCPZ implements a charge redistribution SAR architecture with internal conversion clock and error correction circuitry, eliminating pipeline delay and ensuring deterministic latency (4 μs complete cycle). Its analog front-end supports true bipolar operation via dedicated BIPOLAR/TEN pins and features 75 dB CMRR at 100 kHz.
Digital interfacing is flexible: parallel mode offers 8-/16-bit bus access with BYTESWAP and OB/2C format control, while serial modes include master (internal SDCLK) and slave (external SDCLK) configurations with configurable SYNC polarity (INVSYNC), clock edge (INVSCLK), and read timing (RDC). Configuration is supported via hardware pins or software-accessible serial configuration port (SCCS/SCCLK/SCIN).

Equivalent & Alternatives
The following parts are listed as comparable options for similar SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7612BCPZ | 18-bit resolution, 250 kSPS, same pinout and interface; higher INL (±2.5 LSB max), larger package (48-lead LFCSP, 7 mm × 7 mm). | Targeted at higher-precision applications like metrology and calibration standards where 18-bit resolution justifies increased cost and board area. | Select AD7612BCPZ when ENOB >15.5 is required and layout accommodates identical footprint with enhanced resolution. |
| AD7663ASTZ | 16-bit, 570 kSPS, true bipolar, 48-lead LQFP; no internal reference; requires external 5 V reference; higher power (120 mW @ 570 kSPS). | Used in high-throughput industrial DAQ where speed outweighs reference integration, and external reference stability is already managed. | Choose AD7663ASTZ when throughput >250 kSPS is mandatory and system-level reference architecture exists. |
Compared with AD7610BCPZ, AD7612BCPZ provides 2 additional bits of resolution at identical speed and pin compatibility, while AD7663ASTZ trades integrated reference and lower power for nearly 2.3× higher throughput-making each suitable for distinct precision/speed/power trade-offs in industrial and test systems.

FAQ
What input voltage ranges does the AD7610BCPZ support, and how are they selected?
The AD7610BCPZ supports four input ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V. Selection is performed via hardware using the BIPOLAR and TEN pins (logic combinations per datasheet Table 6), or via software through the serial configuration register when HW/SW = low. This dual-mode flexibility allows fixed-function systems to use pin-strapping while programmable systems retain runtime reconfiguration capability - both methods fully supported on AD7610BCPZ.
Does the AD7610BCPZ require an external reference, or does it include an internal one?
The AD7610BCPZ integrates a 5 V internal reference with typical drift of ±3 ppm/°C over −40°C to +85°C, eliminating the need for an external reference in most applications. When PDREF and PDBUF are both low, the REF pin outputs 5 V (4.965–5.035 V at 25°C). An external reference (4.75–5.25 V) may be used by setting PDREF = high and applying voltage to REF or REFBUFIN - a capability fully documented for AD7610BCPZ in its Rev. B datasheet.
What is the maximum achievable throughput of the AD7610BCPZ, and what limits it?
The AD7610BCPZ achieves a maximum throughput of 250 kSPS, limited by its 4 μs complete conversion cycle (t2 in Table 3). This timing is fixed by the internal SAR architecture and clock generation - not dependent on interface mode. In serial master read-during-convert mode (RDC = high), throughput remains 250 kSPS; in read-after-convert mode (RDC = low), effective throughput drops due to BUSY assertion timing per Table 4 - all performance boundaries are specified and verified for AD7610BCPZ.
Can the AD7610BCPZ operate with a 3.3 V digital interface supply (OVDD)?
Yes, the AD7610BCPZ supports OVDD from 2.7 V to 5.25 V, making it compatible with 3.3 V microcontrollers and FPGAs. Digital I/O levels (VIH/VIL) scale accordingly: VIH minimum is 2.1 V, and VOL maximum is 0.4 V at 500 μA sink - fully compliant with 3.3 V logic families. This OVDD flexibility is explicitly characterized and guaranteed across temperature for AD7610BCPZ.
How is the on-chip temperature sensor used, and what is its accuracy?
The AD7610BCPZ's TEMP pin outputs an analog voltage (311 mV at 25°C) with 1 mV/°C sensitivity, enabled only when the internal reference is active (PDREF = PDBUF = low). Output resistance is 4.33 kΩ, and accuracy is calibrated to ±1°C over −40°C to +85°C. This sensor provides system-level thermal monitoring without external components - a confirmed feature of AD7610BCPZ per its Functional Block Diagram and Pin Descriptions.
