Product details
Overview
AD9070BR-REEL from Analog Devices is a 10-bit, 100 MSPS ECL-output analog-to-digital converter with on-chip track-and-hold, 230 MHz analog bandwidth, –2.5 V internal reference (SOIC), and single –5 V supply operation. It delivers 54 dB SINAD at 41 MHz input and supports digital communications, radar, and spectrum analysis systems requiring high-speed sampling with low aperture jitter (2.5 ps rms).
For engineers reviewing the AD9070BR-REEL datasheet, AD9070BR-REEL pinout, AD9070BR-REEL application, or AD9070BR-REEL equivalent, this page provides verified technical context, package mapping to SOIC-28 (R-28), confirmed ECL-compatible digital outputs, differential encode interface support, and validated alternatives for high-speed data acquisition designs.
Technical Context
The AD9070BR employs a two-step subranging architecture with digital error correction, initiating conversion on the rising edge of ENCODE and delivering latched output data after three pipeline stages (N+3 latency). Its differential analog input amplifier is optimized for single-ended use but supports matched-impedance differential signaling.
It features an integrated –2.5 V bandgap reference (VREF OUT) in the SOIC package, eliminating need for external reference in standard configurations; the differential ENCODE input accepts ECL-level signals with –1 V to –3 V common-mode range and tolerates ±20% pulsewidth variation without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size of 1.024 V full-scale ÷ 1024 = 1 mV per LSB. |
| Sampling Rate | 100 MSPS max - supports Nyquist-limited signal capture up to 50 MHz baseband bandwidth. |
| Analog Bandwidth | 230 MHz - enables accurate digitization of fast-rising RF/IF transients without amplitude roll-off. |
| SINAD @ 41 MHz | 54 dB typical - corresponds to ~8.3 effective bits, confirming usable dynamic range for medium-SNR applications. |
| Aperture Jitter | 2.5 ps rms - limits SNR degradation to ≤0.5 dB at 50 MHz input, critical for undersampling architectures. |
| Power Dissipation | 600 mW typical at 100 MSPS - requires thermal management with θJA = 71°C/W in SOIC package. |
| Digital Interface | ECL-compatible outputs - mandates –2 V pull-down termination for proper logic levels and timing integrity. |
Pinout & Package
AD9070BR is housed in a 28-lead Small Outline IC (SOIC) package, designated R-28, with gull-wing leads, 1.27 mm pitch, and dimensions 18.10 × 10.65 × 2.65 mm (L × W × H). Pin 1 is marked by a beveled corner; device operates over –40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 12, 21, 23 | VEE | Negative power supply (–5 V nominal); all five pins must be connected to minimize ground bounce and supply impedance. |
| 2, 8, 11, 20, 22 | GND | Analog/digital ground reference; shared ground plane required to prevent coupling between sections. |
| 3 | VREF OUT | Internal –2.5 V reference output; bypass to VEE with 0.1 µF capacitor to stabilize reference noise. |
| 4 | VREF IN | Reference input node; shorted to Pin 3 for internal reference use; accepts external –2.5 V source if higher accuracy needed. |
| 5 | COMP | Internal amplifier compensation node; connect 0.1 µF capacitor to VEE to ensure stable T/H loop response. |
| 6 | REF BYPASS | Reference decoupling node; 0.1 µF capacitor to VEE suppresses reference rail noise affecting ADC accuracy. |
| 9, 10 | AIN / AIN | Differential analog input pair; designed for single-ended drive with AIN grounded or biased to match AIN impedance. |
| 13, 14 | ENCODE / ENCODE | Differential clock inputs; sampling occurs on rising edge of ENCODE; supports single-ended drive with proper biasing. |
| 15–19, 24–28 | D0–D9 | 10-bit two's complement digital outputs (D9 = MSB); ECL-compatible, require 100 Ω pull-down to –2 V for valid logic levels. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold | Eliminates need for external T/H circuitry; captures analog signal at precise ENCODE edge with 0.85 ns aperture delay. |
| Integrated –2.5 V reference | Reduces BOM count and layout complexity in SOIC version; supplies 100 µA drive current for auxiliary circuits. |
| Differential encode interface | Enables jitter-immune clock distribution; accepts ECL, PECL, or LVDS with –1 V to –3 V common-mode range. |
| Out-of-range detection | OR signal not present in AD9070BR (SOIC); instead, outputs saturate at 1FFh or 200h during overrange conditions. |
| Three-stage pipeline latency | Ensures deterministic timing: data N appears at D9–D0 on rising edge of ENCODE N+3, simplifying system synchronization. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9288BSTZ-100 | 8-bit, 100 MSPS, CMOS outputs, 3.3 V supply, no internal reference; 200 mW power vs. AD9070BR's 600 mW. | Targeted at lower-resolution, lower-power applications where ECL timing integrity is not required. | Select AD9288BSTZ-100 when system uses CMOS logic, requires lower power, and can accept reduced dynamic range (46 dB SINAD @ 41 MHz). |
| ADS5463IPFP | 13-bit, 500 MSPS, LVDS outputs, 3.3 V supply, on-chip PLL; 1.8 W power; no internal reference; 70 dB SNR @ 10 MHz. | Designed for ultra-high-speed, high-resolution instrumentation and test equipment demanding >10x oversampling. | Choose ADS5463IPFP when resolution >10 bits and sample rate >200 MSPS are mandatory, accepting higher power and board-level clock synthesis complexity. |
Compared with AD9288BSTZ-100 and ADS5463IPFP, the AD9070BR occupies a unique niche: it delivers 10-bit precision at 100 MSPS with ECL timing robustness and integrated –2.5 V reference in SOIC-making it optimal for legacy military/aerospace systems and ECL-based signal intelligence platforms where deterministic latency and jitter control are prioritized over raw resolution or power efficiency.

FAQ
What is the operating temperature range for the AD9070BR-REEL?
The AD9070BR-REEL is specified for industrial temperature operation from –40°C to +85°C. This range is defined in the Ordering Guide and confirmed in the Absolute Maximum Ratings table. The ceramic DIP variant (5962-9756301HXC) extends to –55°C to +125°C, but the AD9070BR-REEL itself is rated only for the industrial grade. Thermal impedance values (θJA = 71°C/W) assume operation within this range.
Does the AD9070BR-REEL include an out-of-range (OR) output pin?
No, the AD9070BR-REEL does not feature an OR output pin. Per the Pin Function Descriptions and Package Comparison section, the OR signal is exclusive to the ceramic DIP version (AD9070DIP). In the AD9070BR-REEL, overrange conditions cause digital outputs D9–D0 to saturate at 1FFh (positive overflow) or 200h (negative overflow) without asserting a dedicated flag.
Can the AD9070BR-REEL operate from a +5 V supply instead of –5 V?
Yes, the AD9070BR-REEL supports +5 V single-supply operation in Positive ECL (PECL) mode. As documented in the "5 V Operation" section, VEE pins connect to ground and all ground pins connect to +5 V; the internal reference becomes +2.5 V referenced to ground, and bypassing must be adjusted accordingly (e.g., COMP and REF BYPASS capacitors tied to ground, not +5 V).
What is the function of Pin 5 (COMP) on the AD9070BR-REEL?
Pin 5 (COMP) is the internal amplifier compensation node for the track-and-hold circuit. The datasheet specifies connecting a 0.1 µF capacitor from Pin 5 to VEE to stabilize the T/H loop and ensure monotonic settling behavior. Omitting this capacitor risks instability, overshoot, or non-monotonic response during hold phase transitions.
Is the AD9070BR-REEL pin-compatible with the AD9070DIP package?
No, the AD9070BR-REEL (SOIC-28, R-28) is not pin-compatible with the AD9070DIP (ceramic DIP-28, DH-28). Although both have 28 leads, their pinouts differ significantly: the DIP includes OR (Pin 28), lacks VREF OUT (Pin 3), and reassigns GND/VEE placements. The datasheet explicitly states separate pin configurations and warns against assuming interchangeability due to functional and mechanical differences.
