TLV2302IP

Overview

The TLV2302IP is a dual-channel mixed-signal device integrating one operational amplifier and one open-drain comparator within an 8-pin PDIP package. It operates on a single supply voltage ranging from 2.5 V to 16 V, with split supply capability up to ±8 V. The unit draws a typical supply current of 1.4 μA at 25°C across the full operating range. The operational amplifier features rail-to-rail input and output capabilities, while the comparator utilizes an open-drain CMOS output stage requiring an external pull-up resistor.

Feature Summary

• Integrates a sub-micropower operational amplifier and an open-drain comparator in a single package for board space reduction.
• Features reverse battery protection allowing inputs and outputs to withstand voltages up to 18 V without damage.
• Supports common-mode input voltages extending 5 V above the positive supply rail (VCC + 5 V).
• Operates with extremely low input bias currents suitable for high-impedance signal sources.

Applications

• Battery-powered portable systems where quiescent current minimization is critical.
• Signal conditioning circuits utilizing mega-ohm resistors due to low input bias currents.
• Industrial applications requiring operation over the extended temperature range of -40°C to 125°C.

Procurement Notes

Verify that the specific part number suffix 'IP' corresponds to the Plastic DIP (PDIP) package variant as documented in the manufacturer's ordering information. Confirm that the industrial grade temperature rating (-40°C to 125°C) aligns with the application requirements. Ensure the design accounts for the open-drain nature of the comparator output, which necessitates an external pull-up resistor to function correctly within the circuit topology.

Selection Notes

Select this component when a combined solution for amplification and threshold detection is required to minimize component count. The device is appropriate for designs powered by Li-Ion batteries or microcontrollers operating at low voltages down to 2.5 V. Consider the trade-off between the slow slew rate and propagation delay against the benefit of ultra-low power consumption. Verify that the required bandwidth does not exceed the specified gain-bandwidth product for the intended application frequency.

Part Context

The TLV2302 belongs to the TLV230x family of nanopower operational amplifiers and comparators manufactured by Texas Instruments. This series is designed to provide excellent micropower signal conditioning capabilities. The family includes variants such as the TLV2304, which offers two amplifiers and two comparators in larger packages. The IP suffix specifically denotes the through-hole plastic DIP packaging option available for this dual-channel configuration.
