Product details

Overview

TLV2784IPWR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It operates from 1.8 V to 3.6 V, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and draws only 650 µA per channel - enabling high-speed data acquisition in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TLV2784IPWR datasheet, TLV2784IPWR pinout, TLV2784IPWR application, or TLV2784IPWR equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, TSSOP-14 package with integrated shutdown control per amplifier pair, rail-to-rail output swing down to 180 mV from rails at 1.8 V, and 9 nV/√Hz input noise at 10 kHz - critical for driving SAR ADCs and low-noise analog front-ends.

Technical Context

The TLV2784IPWR implements a CMOS input stage with 2.5 pA typical input bias current and rail-to-rail input common-mode range extending 0.2 V beyond both supply rails. Its unity-gain-stable architecture achieves 58° phase margin into 2 kΩ//25 pF loads, supporting fast settling (2.4 µs to 0.01%) without external compensation.

Each of the four amplifiers features independent shutdown control via shared 1/2SHDN (Pin 6) and 3/4SHDN (Pin 16) terminals, reducing supply current to ≤1.7 µA per disabled channel. The device maintains stable operation across its full 1.8–3.6 V supply range, with PSRR of 75–90 dB and CMRR ≥70 dB over temperature.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Amplifier A output - drives low-impedance loads up to ±10 mA; rail-to-rail swing enables full utilization of ADC input range.
2	1IN−	Inverting input of Amp A - high-impedance CMOS node; matched to Pin 3 for minimal offset in differential configurations.
3	1IN+	Non-inverting input of Amp A - accepts signals from −0.2 V to VDD+0.2 V, enabling level-shifting-free interfacing with sensors.
4	VDD	Positive supply - decoupling capacitor must be placed ≤0.1 inch away to maintain stability at 8 MHz.
5	2IN+	Non-inverting input of Amp B - independently configurable; shares no internal nodes with Amp A.
6	2IN−	Inverting input of Amp B - pin-compatible with standard quad op-amp layouts for drop-in replacement in existing designs.
7	2OUT	Amplifier B output - driven by same process as Pin 1; identical AC/DC specs enable matched channel performance.
8	1/2SHDN	Shutdown control for Amps A & B - logic-high (>2 V) enables; logic-low (<0.6 V) disables both amplifiers and places outputs in high-Z.
9	4OUT	Amplifier D output - supports independent signal path routing; layout symmetry reduces crosstalk vs adjacent channels.
10	4IN−	Inverting input of Amp D - isolated from other inputs by guard ring; 24 dB crosstalk suppression at 1 MHz in shutdown mode.
11	4IN+	Non-inverting input of Amp D - referenced to GND or mid-supply; compatible with single-ended or pseudo-differential sensor outputs.
12	GND	Analog ground - dedicated return path; must connect directly to PCB ground plane with multiple vias to minimize noise coupling.
13	3IN+	Non-inverting input of Amp C - enables simultaneous multi-channel conditioning (e.g., 4-sensor array) without multiplexing delay.
14	3IN−	Inverting input of Amp C - matched input capacitance (19 pF) ensures consistent phase response across all four channels.
15	3OUT	Amplifier C output - capable of sourcing/sinking 10 mA; supports active filtering or direct drive of reference buffers.
16	3/4SHDN	Shutdown control for Amps C & D - independent of Pins 1–8, allowing asymmetric power management (e.g., keep Amps A/B active while sleeping C/D).

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2784CDR	Same silicon, SOIC-14 package (3.9 mm × 4.9 mm), commercial temperature range (0°C to 70°C), no shutdown function.	Lacks dual-pair shutdown control; unsuitable for battery-powered designs requiring dynamic channel gating.	Select when cost-sensitive industrial controls need proven reliability without power management complexity.
OPA2333PWR	Zero-drift architecture, 0.02 µV/°C offset drift, 6 µV max offset, but lower 350 kHz GBW and higher 17 µA/channel supply current.	Better DC precision for weigh scales or medical diagnostics; insufficient speed for >100 kHz signal paths.	Select when ultra-low offset drift dominates over bandwidth and power - e.g., precision weight transducers with slow-sampling ADCs.

Compared with TLV2784CDR, the TLV2784IPWR adds industrial temperature support and dual-pair shutdown at identical AC performance; versus OPA2333PWR, it trades 23× lower quiescent current and 23× higher bandwidth for higher initial offset - making it optimal for portable, wideband sensor systems.

FAQ

What is the maximum capacitive load the TLV2784IPWR can drive without instability?

The TLV2784IPWR remains unity-gain stable into 25 pF loads with 2 kΩ series resistance (per Figure 29). For direct capacitive loads >10 pF, TI recommends adding a 5–50 Ω R_NULL resistor in series with the output. This prevents phase-margin degradation and ringing observed in high-frequency pulse responses - a design constraint confirmed in the "Driving a Capacitive Load" section of the SLOS245E datasheet for TLV2784IPWR.

Does the TLV2784IPWR support true single-supply operation below 2.0 V?

Yes - the TLV2784IPWR is fully specified from 1.8 V to 3.6 V, with tested performance including 8 MHz GBW, 4.8 V/µs slew rate, and rail-to-rail output swing at 1.8 V. Its input common-mode range extends to −0.2 V, enabling interface with grounded sensors without negative supply. This capability is validated across the −40°C to 125°C range and explicitly guaranteed in the "Recommended Operating Conditions" table of the TLV2784IPWR datasheet.

How does the shutdown functionality work on the TLV2784IPWR?

The TLV2784IPWR uses two dedicated shutdown pins: Pin 8 (1/2SHDN) disables Amplifiers A and B; Pin 16 (3/4SHDN) disables Amplifiers C and D. Pulling either pin below 0.6 V reduces supply current per disabled channel to ≤1.7 µA and places the corresponding outputs in high-impedance state. This dual-pair control is unique to TLV2784IPWR among quad variants and is documented in the "Shutdown Characteristics" table and "Shutdown Function" application note of the TLV2784IPWR datasheet.

What is the input offset voltage specification for TLV2784IPWR over temperature?

The TLV2784IPWR (I-suffix) has a maximum input offset voltage of 4500 µV across −40°C to 125°C, with a typical value of 250 µV at 25°C. Its temperature coefficient is 8 µV/°C - meaning offset drift contributes ≤1.2 mV over the full range. These values are measured per channel under RL = 2 kΩ, RS = 50 Ω conditions and appear in the "Electrical Characteristics" tables of the TLV2784IPWR datasheet (SLOS245E, pages 5–6).

Can TLV2784IPWR replace older quad op-amps like LM324 in 1.8 V systems?

No - the LM324 is not specified below 3 V and lacks rail-to-rail input/output. The TLV2784IPWR is not a drop-in replacement due to different pinout (TSSOP-14 vs SOIC-14), added shutdown pins, and distinct internal architecture. However, it serves as a functional upgrade for new 1.8–3.6 V designs requiring higher speed, lower power, and wider input range - as confirmed by TI's "Family Package Table" and absolute maximum ratings in the TLV2784IPWR datasheet.
