Product details
Overview
AD8515ARTZ-REEL7 from Analog Devices is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-voltage, low-power operation. It delivers 5 MHz gain bandwidth, 2.7 V/μs slew rate, and 450 μA maximum supply current at 1.8 V - enabling precision signal conditioning in space-constrained, battery-powered sensor interfaces and portable communications systems.
For engineers reviewing the AD8515ARTZ-REEL7 datasheet, AD8515ARTZ-REEL7 pinout, AD8515ARTZ-REEL7 application, or AD8515ARTZ-REEL7 equivalent, key selection criteria include its 1.8 V minimum supply, 6 mV max offset voltage, rail-to-rail swing, −40°C to +125°C operating range, and SC70/SOT-23 package compatibility for high-density PCB layouts.
Technical Context
The AD8515ARTZ-REEL7 uses a complementary differential input stage (PMOS/NMOS) enabling true rail-to-rail common-mode input range (0 V to VS) and output swing within 10 mV of rails under 750 µA load. Its 0.6 µm CMOS process achieves stable 5 MHz unity-gain bandwidth across 1.8 V–5 V supplies with <4 µV/°C offset drift.
It features no phase reversal up to ±6 V differential input, robust 4 kV HBM ESD tolerance, and inherent stability driving capacitive loads up to 500 pF in unity gain - eliminating need for external compensation in most sensor buffering and filter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.0 V - operates down to end-of-discharge voltage of Li-ion (1.7 V), NiMH (1.0 V), and alkaline (1.1 V) cells. |
| Gain Bandwidth Product | 5 MHz - supports accurate 100 kHz band-pass filtering and stable closed-loop gain ≥10 at audio and ultrasonic frequencies. |
| Slew Rate | 2.7 V/μs - enables clean 130 kHz sine-wave generation in Wien bridge oscillators without clipping. |
| Input Offset Voltage | 6 mV maximum (25°C), 8 mV over −40°C to +125°C - ensures ≤0.5% error in 12-bit ADC front-ends with 1 V full-scale reference. |
| Supply Current per Amplifier | 450 μA maximum at 1.8 V - draws only 0.81 μW per amplifier, critical for multi-sensor nodes with >1-year battery life. |
| Input Bias Current | 2 pA typical at 1.8 V - allows use with >1 MΩ source impedances (e.g., piezoelectric sensors, pH electrodes) without significant DC error. |
| Common-Mode Rejection Ratio | 50 dB minimum (−40°C to +125°C) - maintains accuracy in noisy industrial environments with ground offsets up to 100 mV. |
Pinout & Package
AD8515ARTZ-REEL7 is supplied in a 5-lead SOT-23 (RJ-5) package per JEDEC MO-178-AA, with 1.90 mm × 2.95 mm footprint and 1.30 mm height. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail swing (10 mV to VS − 20 mV) into 750 µA load; drives 500 pF capacitive loads directly. |
| 2 - V− | Negative supply | Ground reference for single-supply operation; accepts 0 V minimum; must be decoupled with 0.1 µF ceramic capacitor. |
| 3 - +IN | Noninverting input | High-impedance node (2 pA bias); connects to sensor outputs or resistor dividers for mid-supply biasing. |
| 4 - −IN | Inverting input | High-impedance node; used for feedback networks in transimpedance, difference, or active filter configurations. |
| 5 - V+ | Positive supply | Accepts 1.8 V to 5.0 V; internal ESD protection clamps to V+ and V−; requires local 0.1 µF bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization with 1.8 V supplies - e.g., 0–1.8 V output swing preserves SNR in 12-bit SAR ADC drivers. |
| Low 1.8 V supply current | 450 μA max per amplifier - reduces thermal load in stacked sensor modules and extends coin-cell battery life beyond 2 years. |
| No phase reversal | Operates safely with inputs exceeding V+ or dropping below V− by up to 0.6 V - eliminates latch-up risk in transient-prone automotive sensor lines. |
| Capacitive load drive | Stable with 500 pF in unity gain - simplifies design of anti-aliasing filters and eliminates need for isolation resistors in DAC output buffers. |
| Extended temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes. |
Applications
| Portable Sensor Interface | Laser Scanner Signal Chain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Lower GBP (1 MHz), higher offset (1.5 mV typ), same 1.8 V min supply and SOT-23 package. | Insufficient bandwidth for 100 kHz filter or oscillator designs; suitable only for DC-coupled sensor amplification. | Select when cost sensitivity outweighs speed requirements and 1 MHz bandwidth suffices. |
| TSV911ICT | Higher supply current (800 μA @ 1.8 V), wider GBP (8 MHz), but only rated to +85°C. | Not qualified for extended industrial or automotive ambient temperatures; better for consumer-grade portable devices. | Choose when higher speed is needed and operating temperature stays below 85°C. |
Compared with MCP6001T-E/OT and TSV911ICT, AD8515ARTZ-REEL7 uniquely balances 5 MHz bandwidth, 450 μA supply current, and −40°C to +125°C qualification - making it the only option for high-precision, wide-temperature, low-power signal chains where both speed and efficiency are non-negotiable.

FAQ
What is the maximum operating temperature for AD8515ARTZ-REEL7?
The AD8515ARTZ-REEL7 is fully specified from −40°C to +125°C, with electrical characteristics guaranteed across this extended industrial temperature range. Its thermal resistance (θJA = 230°C/W for SOT-23) and junction temperature limit of +150°C allow reliable operation in under-hood automotive and industrial motor control environments where ambient temperatures exceed 100°C.
Does AD8515ARTZ-REEL7 support true rail-to-rail input at 1.8 V supply?
Yes, AD8515ARTZ-REEL7 supports rail-to-rail input common-mode range from 0 V to VS (1.8 V) at all temperatures. Its complementary PMOS/NMOS input stage eliminates dead zones near the rails, enabling accurate amplification of signals such as battery voltage monitoring (0–1.8 V) or thermistor divider outputs without level-shifting circuitry.
Can AD8515ARTZ-REEL7 drive a 500 pF capacitive load in unity gain?
Yes, AD8515ARTZ-REEL7 is internally compensated to remain stable driving up to 500 pF in unity-gain configuration, as verified in Figure 32 of the Rev. E datasheet. This eliminates external isolation resistors in DAC output buffers and anti-aliasing filters, reducing component count and board area in space-constrained designs.
What is the typical input bias current of AD8515ARTZ-REEL7 at 1.8 V?
The typical input bias current of AD8515ARTZ-REEL7 is 2 pA at 1.8 V and 25°C, with a maximum of 30 pA. This ultra-low value enables direct interfacing with high-impedance sources like piezoelectric sensors, pH electrodes, and photodiodes without significant DC error or signal attenuation - critical for precision measurement front-ends.
Is AD8515ARTZ-REEL7 RoHS compliant?
Yes, AD8515ARTZ-REEL7 is RoHS compliant, as indicated by the "Z" suffix in its ordering code per Analog Devices' Ordering Guide. It meets EU Directive 2011/65/EU and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
