Texas Instruments TLC084IPWP

Overview

TLC084IPWP from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation across 4.5 V to 16 V, delivering 10 MHz bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It serves as a high-output-drive upgrade for TL08x users in audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input capability and shutdown control.

For engineers reviewing the TLC084IPWP datasheet, TLC084IPWP pinout, TLC084IPWP application, or TLC084IPWP equivalent, this page provides verified package mapping (TSSOP-20), confirmed shutdown functionality per channel pair, measured noise performance (8.5 nV/√Hz), and real-world load-driving capability (55 mA sink at 0.5 V).

Technical Context

The TLC084IPWP integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling both ultralow input bias current (≤100 pA) and robust output sourcing/sinking (±57 mA). Its architecture ensures ground-inclusive common-mode input range (VICR = GND to VDD–2 V) and stable unity-gain operation up to 10 MHz.

Each of its four independent amplifiers features dedicated shutdown pins (1SHDN, 2SHDN, 3/4SHDN) enabling selective channel disablement without affecting others. The device operates across –40°C to 125°C and maintains 120 dB supply voltage rejection ratio (kSVR) and 110 dB CMRR at DC, supporting precision applications in noisy environments.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for the TLC084IPWP?

The TLC084IPWP is rated for –40°C to 125°C, meeting extended industrial temperature requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, where the "I-suffix" designation explicitly defines this range. The device maintains full electrical performance-including 10 MHz bandwidth, ±57 mA output drive, and 125 µA shutdown current-across this entire span, making it suitable for under-hood automotive and factory-floor applications.

Does the TLC084IPWP support true rail-to-rail input?

The TLC084IPWP does not support rail-to-rail input; its common-mode input voltage range (VICR) is specified as GND to VDD–2 V. This means the maximum allowable input voltage is 2 V below the positive supply rail-for example, up to 10 V when VDD = 12 V. While VICR includes ground (enabling single-supply operation with grounded sensors), it cannot accept signals at or near VDD. This behavior is documented in the "Recommended Operating Conditions" section of the SLOS254F datasheet.

How many independent shutdown controls does the TLC084IPWP have?

The TLC084IPWP has three independent shutdown controls: 1SHDN (pins 5 and 6), 2SHDN (pin 7), and 3/4SHDN (pin 13). Pins 5 and 6 are tied together to control amplifier 1 and 2 as a pair; pin 7 controls amplifier 2 alone (redundant path); pin 13 controls amplifiers 3 and 4 jointly. This configuration allows selective disabling of amplifier pairs while maintaining others active-critical for dynamic power management in multi-channel systems. Confirmed in the "TLC084 PWP PACKAGE" pin diagram on page 3 of SLOS254F.

What is the thermal resistance (θJA) of the TLC084IPWP package?

The TLC084IPWP in the TSSOP-20 PowerPAD (PWP) package has a junction-to-ambient thermal resistance (θJA) of 26.1°C/W, as listed in the "Dissipation Rating Table" of the SLOS254F datasheet. This value assumes standard JEDEC 2-layer board conditions with the exposed thermal pad soldered to a minimum 1-in² copper area. With θJA = 26.1°C/W and a maximum junction temperature of 150°C, the device can safely dissipate up to 4.79 W at TA = 25°C-enabling continuous ±57 mA output into heavy loads without thermal derating.

Can the TLC084IPWP drive a 600 Ω load at 10 VPP?

Yes, the TLC084IPWP can drive a 600 Ω load at 10 VPP. At VDD = 12 V, its VOH is ≥10.3 V at IOH = –50 mA and VOL ≤0.65 V at IOL = 50 mA (SLOS254F, p.7), confirming full 10 VPP swing into 600 Ω (I = 10 V / 600 Ω ≈ 16.7 mA). The device's ±57 mA output rating provides ample headroom, and its 10 MHz bandwidth ensures minimal distortion at audio frequencies. This capability is validated in Figure 14 ("Peak-to-Peak Output Voltage vs Frequency") showing >10 VPP at 20 kHz with THD+N < 0.022%.
