AD8336ACPZ-RL

Overview

The AD8336ACPZ-RL is a low-noise, single-ended, linear-in-dB variable gain amplifier in a 16-LFCSP-VQ package. It features an uncommitted preamplifier with a usable gain range of 6 dB to 26 dB and a VGA gain range of 0 dB to 60 dB. The device operates over supply voltages from ±3 V to ±12 V and temperatures from −55°C to +125°C. Small-signal bandwidth reaches 115 MHz, while large-signal bandwidth is 80 MHz at 2 V p-p. Gain scaling is 50 dB/V, with absolute gain limits of −26 dB to +34 dB.

Feature Summary

• X-AMP architecture maintains frequency response across the entire gain range.
• Differential gain control interface provides precise linear-in-dB adjustment.
• Fully independent voltage feedback preamplifier supports inverting and noninverting topologies.
• PWRA pin allows quiescent power reduction for high-voltage applications.

Applications

• Industrial process controls
• High performance AGC systems
• I/Q signal processing
• Video circuits
• Radar receivers

Procurement Notes

Verify the specific suffix RL against the manufacturer's ordering guide to confirm tape and reel packaging specifications. Ensure the component matches the required temperature grade and supply voltage range for the target application environment. Cross-reference the datasheet revision to confirm current electrical characteristics before finalizing procurement.

Selection Notes

Select this component when wide dynamic range and DC coupling are required. The dual-supply operation accommodates bipolar input signals from sensors like photodiodes. Consider the preamplifier offset voltage if operating at maximum gain, as it is amplified by the total system gain. Evaluate load conditions carefully at higher supply voltages to prevent exceeding safe operating limits.

Part Context

This part belongs to the AD8336 family of general-purpose variable gain amplifiers. It utilizes the X-AMP architecture to deliver consistent performance over extreme temperature and supply voltage variations. The device integrates a preamplifier and a VGA stage, offering flexibility in gain configuration through external resistors.

FAQ

How is the preamplifier gain configured?

The preamplifier gain is set using external resistors in a standard operational amplifier configuration, allowing for gains between 6 dB and 26 dB.

What is the effect of the PWRA pin?

Asserting the PWRA pin reduces the quiescent power consumption and bandwidth by approximately half, which is beneficial for high-voltage supply applications.
