Analog Devices Inc. AD8032ANZ

Overview

AD8032ANZ from Analog Devices is a dual, rail-to-rail input/output voltage feedback operational amplifier optimized for high-speed, low-power applications. It delivers 80 MHz −3 dB bandwidth (G = +1), 30 V/μs slew rate, and 125 ns settling time to 0.1% while consuming only 800 μA per amplifier at +5 V supply. It operates from +2.7 V to +12 V single supply or ±1.35 V to ±6 V dual supply and is widely used as an A/D converter buffer in portable test instruments and battery-powered systems.

For engineers reviewing the AD8032ANZ datasheet, AD8032ANZ pinout, AD8032ANZ application, or AD8032ANZ equivalent, key selection criteria include rail-to-rail I/O swing within 20 mV of rails, low distortion (−86 dBc @ 100 kHz, 4.6 V_p-p), crosstalk performance (−60 dB @ 5 MHz), input common-mode range extending 200 mV beyond supplies, and guaranteed operation over −40°C to +85°C industrial temperature range.

Technical Context

The AD8032ANZ employs a proprietary eXtra Fast Complementary Bipolar (XFCB) process and dual-input-stage architecture-switching between PNP and NPN differential pairs-to maintain transconductance and bandwidth across rail-to-rail input common-mode range (−0.2 V to +5.2 V on +5 V supply). This eliminates phase reversal up to 500 mV beyond either rail.

Its rail-to-rail output stage uses common-emitter transistors with ~25 Ω effective collector resistance, enabling 15 mA output drive and output swing to within 20 mV of rails under light load. Open-loop gain remains stable within 250 mV of V_CC and 150 mV of V_EE, then decreases linearly as output transistors saturate.

Key Specifications

Pinout & Package

AD8032ANZ is packaged in an 8-lead PDIP (Plastic Dual In-line Package) with standard through-hole mounting. The package has 0.3 inch body width, 0.1 inch lead pitch, and is rated for industrial temperature operation (−40°C to +85°C).

FAQ

What is the maximum operating supply voltage for AD8032ANZ?

The AD8032ANZ supports a single supply range of +2.7 V to +12 V and dual supplies from ±1.35 V to ±6 V. Absolute maximum supply voltage is 12.6 V. Exceeding this risks permanent damage. Operation at +12 V is valid but increases quiescent current to ~1.4 mA per amplifier and requires thermal derating per Figure 7 in the datasheet.

Does AD8032ANZ support true rail-to-rail input with phase reversal immunity?

Yes. The AD8032ANZ input common-mode voltage range extends from −0.2 V to +5.2 V on a +5 V supply - 200 mV beyond each rail - and exhibits no phase reversal for inputs up to 500 mV beyond either supply. This behavior is guaranteed by its dual-input-stage architecture and is verified across the full −40°C to +85°C temperature range.

Can AD8032ANZ drive a 50 Ω load directly?

No. AD8032ANZ is specified for 15 mA continuous output current and 20 mV rail margin into 10 kΩ. Driving 50 Ω would require 100 mA at 5 V swing, exceeding its capability and causing severe clipping and thermal stress. Use an external buffer (e.g., high-current line driver) or series termination for 50 Ω interfaces. The AD8032ANZ datasheet explicitly limits capacitive load drive to 15 pF at G = +2.

What is the guaranteed input offset voltage specification for AD8032ANZ?

The AD8032ANZ is part of the AD8032A grade, with maximum input offset voltage of ±1.5 mV at 25°C and ±2.5 mV over the full −40°C to +85°C temperature range. This is confirmed in Table 1 (+2.7 V supply) and Table 2 (+5 V supply) of Rev. G datasheet. The "N" suffix denotes PDIP packaging; "ANZ" indicates lead-free, RoHS-compliant variant.

Is AD8032ANZ pin-compatible with other members of the AD803x family?

Yes. AD8032ANZ shares identical 8-lead PDIP pinout with AD8032ARZ (SOIC_N) and AD8032ARMZ (MSOP), differing only in package type and thermal characteristics. All variants use the same connection diagram (Figure 2), with pins 1–4 and 5–8 assigned identically. No PCB redesign is needed when migrating between these packages, though layout must accommodate different thermal pads and solder profiles.
