Product details

Overview

AD8619ARZ-REEL7 from Analog Devices is a quad micropower, rail-to-rail input/output operational amplifier optimized for low-noise, low-voltage portable instrumentation. It delivers 22 nV/√Hz voltage noise density at 10 kHz, 50 μA/amplifier max supply current over temperature, and 2.2 mV max offset voltage across −40°C to +125°C - enabling precision signal conditioning in battery-powered sensor front-ends and ADC predrivers.

For engineers reviewing the AD8619ARZ-REEL7 datasheet, AD8619ARZ-REEL7 pinout, AD8619ARZ-REEL7 application, or AD8619ARZ-REEL7 equivalent, key selection criteria include its 1.8 V to 5.5 V single-supply operation, rail-to-rail I/O swing, 400 kHz gain bandwidth, and qualification for automotive-grade reliability per AD8619W specifications.

Technical Context

The AD8619ARZ-REEL7 implements a CMOS input stage with 1 pA max input bias current and 2.5 pF common-mode input capacitance, supporting high-impedance sensor interfacing without significant loading. Its unity-gain stable architecture achieves 70° phase margin with 20 pF capacitive load and maintains rail-to-rail output swing down to 30 mV from rails at 1 mA load.

Designed for operation from 1.8 V to 5.5 V single supply (or ±0.9 V/±2.5 V dual), it features no phase reversal under overdrive and supports stable performance across −40°C to +125°C ambient - validated in both SOIC_N and TSSOP packages per JEDEC MS-012-AB and MO-153-AB-1 standards.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.8 V to 5.5 V single supply - enables direct interface with Li-ion, coin-cell, and low-voltage ASICs without level-shifting.
Input Offset Voltage	2.2 mV maximum over −40°C to +125°C - ensures <±0.5% error in 12-bit ADC predriver applications at 5 V full-scale.
Supply Current per Amplifier	50 μA maximum over temperature - allows four-channel operation at <200 μA total, critical for multi-sensor IoT nodes.
Voltage Noise Density	22 nV/√Hz at 10 kHz - minimizes contribution to system noise floor in 1–10 kHz sensor bandwidths.
Gain Bandwidth Product	400 kHz at RL = 100 kΩ - supports stable closed-loop gain of ≥10 up to 40 kHz for anti-aliasing filter stages.
Common-Mode Rejection	68 dB minimum over −40°C to +125°C - maintains accuracy when sensing shunt voltages near supply rails.
Output Swing	Rail-to-rail: VOL ≤ 50 mV and VOH ≥ 4.9 V at 1 mA load (5 V supply) - preserves dynamic range for 16-bit DAC drivers.

10	−IN D	Inverting input of Amplifier D - identical electrical characteristics to Pins 1 and 5; supports quad-channel synchronous sampling.
11	+IN D	Non-inverting input of Amplifier D - matched layout to minimize thermal drift mismatch between channels.
12	V−	Negative supply rail - redundant connection; ties to Pin 8 for mechanical robustness and current sharing.
13	OUT C	Output of Amplifier C - designed for unity-gain stable operation with 20 pF capacitive load per datasheet Figure 18.

FAQ

What is the operating temperature range for the AD8619ARZ-REEL7?

The AD8619ARZ-REEL7 is specified for continuous operation from −40°C to +125°C ambient temperature. This range is validated per the Absolute Maximum Ratings table and supported by electrical characteristics tested across this span, including offset voltage drift of 1–4.5 μV/°C and supply current up to 50 μA per amplifier. The device uses the standard commercial-grade SOIC_N package (R-14) and is not automotive-qualified unless marked 'W' (e.g., AD8619WARZ-RL).

Does the AD8619ARZ-REEL7 support true rail-to-rail input and output operation?

Yes, the AD8619ARZ-REEL7 supports rail-to-rail input common-mode voltage range (0 V to V+) and rail-to-rail output swing. At 5 V supply and 1 mA load, output voltage low (VOL) is ≤50 mV and output voltage high (VOH) is ≥4.9 V. Input voltage range extends to within 0.3 V of either rail, enabling direct interfacing with CMOS logic and low-voltage ADCs/DACs without external level-shifting circuitry - a core feature confirmed in the General Description and Electrical Specifications sections.

What is the maximum supply current per amplifier for the AD8619ARZ-REEL7?

The maximum supply current per amplifier for the AD8619ARZ-REEL7 is 50 μA over the full −40°C to +125°C temperature range, as specified in Table 1 under "Supply Current/Amplifier" (ISY). At 25°C and 5 V supply, typical current is 38 μA. This micropower characteristic enables four-channel operation below 200 μA total, making AD8619ARZ-REEL7 suitable for always-on sensor nodes and energy-harvesting applications where quiescent power is critical.

Can the AD8619ARZ-REEL7 drive capacitive loads without instability?

The AD8619ARZ-REEL7 is unity-gain stable and characterized for capacitive loads up to 20 pF, with 70° phase margin maintained at both 10 kΩ and 100 kΩ loads per Figure 14. For loads exceeding 20 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to preserve stability. The datasheet confirms stable transient response in Figures 19–20 and small-signal overshoot data in Figures 18 and 33 - validating its use in ADC driver and filter applications with moderate capacitive back-ends.

Is the AD8619ARZ-REEL7 pin-compatible with other devices in the AD861x family?

No, the AD8619ARZ-REEL7 is not pin-compatible with AD8613 or AD8617 variants due to differing channel counts and package footprints: AD8613 is single-channel (5-lead SC70/TSOT-23), AD8617 is dual-channel (8-lead MSOP/SOIC/LFCSP), and AD8619ARZ-REEL7 is quad-channel in 14-lead SOIC_N. Pin mapping follows the dedicated 14-pin layout shown in Figure 4, with dedicated V− pins (8 and 12) and distributed amplifier inputs/outputs - requiring unique PCB layout versus other family members.
